If you are on the comp a lot I suggest an e-business...Don't really know what you are able to take on but if you can type ( meaning at a good speed 70 and higher per min)you can find plenty of people looking for data entry and website updating....

Like my sisters friend who makes tons just updating mailing list for people who own a few weight loss centers and sell products like medifast on the internet....It is effortless...I mean this is a real business she owns...This is all she does...even has employees

Hope that helps a little
