I need to find a technical reviewer for a programming document.
I have looked on Craigslist and various freelancers' websites (RentACoder, Odesk, Elance, etc) but it's difficult to determine who is qualified to act as a reviewer.
The last thing I need is to have the document reviewed by someone who either doesn't know what they are talking about or is not willing to go to the trouble of reviewing the document thoroughly.
An ineffective review might be worse than no review at all since it might generate a false sense of completion.
Any tips on selecting someone qualified & reliable?
