Does anyone know any places to work online?

I need some extra income for me and my kiddo, and I'd be happy to do extra work, but I'm having trouble finding work that will accept my irregular schedule. I'd love to do work online where I set my own hours, so I can work at night and some weekends and get some money. I'm looking for legitimate places, potentially long term, and I have education and experience in Information Technology, Retail and Customer Service.

Thanks in advance :D
