I can give you some advice from experience.... You say you can't imagine working outside the home right now, so I have to make some assumptions--- are you saying that mainly because you don't want your kids in day care? If that is what you mean, imagine this.... if you were working outside the home in an office, how much would you get done if you had your kids there with you?? Now multiply that by the chores that are calling for you to be done. What I'm telling you is that I can tell you from experience that it is VERY VERY VERY difficult to get any work done while your kids are home with you. It's next to impossible to make phone calls (think about how it is now when you want to chat with a friend or relative, then imagine that as a business call when you need silence and concentration and zero distractions during the call!) and very difficult to focus on anything regarding paperwork or computer while your kids want your nearly constant attention. Think about reading a magazine during a typical day home with the kids... You start on an article and the baby needs to be fed-- you try to feed her while you read the magazine but it's hard to turn the pages while you hold her. It can be done, but it's difficult... Then you set her down for some tummy time or a nap and your son needs lunch...and a snack... and more to drink...and help in the bathroom...and your attention playing...and the washing machine just buzzed so you need to throw it in the dryer... and you keep thinking about how you want to drop what you're doing for just a few minutes to prep what you're making for dinner... and while you were in the bathroom you noticed how grimey it was and it's killing you that you can't drop absolutely everything to clean it this very second...and when was the last time you mopped the floor....etc, etc, etc! It;s much harder than people think to work from home. You have to be very disciplined, very organized, and for most jobs you WILL need to either have your children out of the house (in some sort of day care) or have someone in your home watching them while you work (husband, grandma, or paid babysitter). I am not trying to discourage you from trying-- I just want to make sure you and anyone else reading this who is contimplating a work from home career understands the reality of it. You end up spending less money on things like the communte, eating out for lunch, buying expensive coffee drinks, make up, new clothes, dry cleaning, etc. so if you can make it work I say go for it...But just keep in mind that you more than likely WILL need someone to watch your kids while you work, and there is a huge sense of feeling out of the loop in the work-from-home world. If others in your company work in an office, they tend to forget about you sometimes and go "oh, you didn't know that? We covered it at last week's meeting".
Now that I've covered the Ree Al Uh T of being a work from home mom... here is an idea you can look into...
If you are truely motivated to make this work, you need to pound the pavement for clients. My mom assists elderly friends of her's with their managing of their own personal financial affairs. Since your clients wouldn't be personal friends, you may have to look into getting some sort of bonding or licence or something, but it's worth it if you can make it happen. You basically appraoch nursing homes and assisted living facilities (or even better if you personally know anyone who you can start with and they can recommend you to their friends and it snowballs from there by word of mouth)... What my mom does is she takes several months of bank books and balances their accounts and makes sure all billd are being paid on time. She has also called companies on their behalf to help minimize or elliminate fees. She has discovered bills they have been paying that can be consolidated or reduced in some way for various reasons. She ends up saving them lots of money in the long run, so they don't mind paying her at all. I think she charged something like $20-25 an hour for the first time when she sits down with the client (and depending on the client, sometimes she has realtives of the client sit with them-- so they can see that she is not trying to steal from them and they can see how awesome she is!), and then once the client establishes how much and how often they need her then she charges a basic fee once a month when she meets with them. My mom works really well with and is very comfortable with the elderly, so she visits her clients in between visits, like if she is at the facility to work for a client and she has another client at the same facility, she will schedule time to make sure it's not just a pop in of hello but real time to sit and visit. Her clients all appreciate her genuine personality and time she gives them and they trust her and recommend her to others.
Good luck with whatever you decide to do. So many of us struggle with being a SAHM and the financial burden of it... but it's only for a few years and then your kids are in school full time and you can always go back to work then, so be sure to cherish this time you have with them. Look at ALL of your monthly bills and see if there is a way to cut back on any of them. Do you really need that bundle on your phone that includes call forwarding and other features you never use? Can your family make the ultimate sacrifice and not have cable for a few years? Pinch pennies wherever you can and you may end up making more money than if you worked and all of the hidden expenses that come from working....
