Anyone ever use Rent-A-Coder or any like services?

I'm at the point in a project where I have to accept that I'm not going to learn how to code in a particular language anytime soon.
Need to find freelance coder to handle what should be a simple job ( I know, I hate when people say that too).

Anyone every use Rentacoder or anything like it? I have an apprehension to freelance sites for my own industry, so I have no idea what to expect.

Any ideas or suggestions?
