Right now, you don't need to get rich. You need to get some of the pressure off and get stable. If you can reasonably land a six-figure job which you can stand doing for a few years, DO IT.

Desperate and looking for get-rich-quick schemes is not conducive to successful entrepreneurship. Most successful businesses take years to build, and most business ventures are not successful. You should consider whether it can be a part of your ongoing career plans, but it's not a likely solution to your immediate problems.
