Extra money

You seem to have a time disadvantage when it comes to making some extra cash. But... It seems you may have the advantage of interaction with lots of people. If I were in your place, I would be looking for something I could sell to the people I already interact with. I would want a consumable product, low cost, with a good profit margin. That's what I do now with the people I know and work with. Depending on how ambitious I'm feeling, I can make as much as several hundred extra every month with little effort.
