How about doing something in the Real Estate office such as administrative support for some of the Realtors?
If Real Estate is your focus for your career, I would try anything in any office to help learn the system such as mortgage brokers, title companies, etc and do admin work along with your Real Estate to supplement your income.
I don't know how the job market is in your area but around here it is very good.
Another good option is to take a course such as Dale Carnegie which can help you brush up your skills for sales and communication.
Instead of joining an MLM/Direct sales, etc which would draw your focus away from your real estate, I would continue to focus on real estate potential opportunities.
A good way to get part time or get in the door for many places is to work with a temp agency. I come from a marketing background for a MAJOR salty snack company and we hired all of our admins from the temporary pool of people we had. This worked great because we knew the people and if they fit with us or not and same goes for the temp person... they got a feel for our company and could decide if they wanted to work for us or not.
Are you on LinkedIn.com? it is a great networking site. I get a lot of resumes from potential employees and I also get a lot of hits from recruiters from my site. We own our company and it is vital to keep up with the networking.
Best wishes!
