Websites where you edit and advise on resumes?

I’m really good at resume editing and help hire a lot of people at my firm, so I know what employers are looking for. I’ve previously run a few workshops for young professionals.

Are there online services that offer part-time jobs that help edit and advise people on their resumes? I previously saw someone on MSNBC Money talk about how they do this part-time online but couldn’t find anything online.
