What kind of "double master" do you have? Sorry, I did not go back and read your previous postings.
Working from home is WORK. So IF you happen to find something that is legit, Hard to do, then you will have to work when your children are in school, in bed, or in the care of someone else. As someone who owns a company and works from home, I will not hire someone to work for me while they are watching their children. I could never do my job with children around because it is critical to not make a mistake or I could cost our company (family) thousands of dollars. We are in raw materials and distribution and one screw up could shut a manufacturer down which could result in lawsuits as well. You have to have the A game on 24/7 when working at home with NO distractions (including pets).
If anyone ask you for money so you can go to work for them or get qualified, RUN it is a scam. You already know that.
Look at your "double masters" and how can they help you. Are you a teacher? Numerous opportunities are available for qualified tutors of academics, languages, instruments, etc.
Figure out your niche... are you crafty? Create and sell on Etsy.
Just beware of anything that comes close to indicating that you will be paid high dollar for little work. Network with your friends, friends of friends, LinkedIn and other social media so people know your qualifications and desire to have extra work.
There is always the option of going retail for the season but of course you have to offset child care so weigh those options carefully.
Best wishes to you.
