Questions on part time editing

I was lamenting my lack of money with a friend of mine and he said that there was a relatively large market for freelance or part time video editing work. I was wondering if anyone here does that kind of thing and would be willing to give me some guidance. I absolutely love editing and if I can get paid for it that would be amazing. I just don't know where to start. Are there resources or websites where I can get gigs like this? How do I advertise myself? What's a competitive rate? I would appreciate any help the community can give me about how to get started. Thanks!
