You can send link to candidates asking them to do some coding tests. From as simple as reverse a string, FizzBuzz to more difficult ones.

That way you can pick the best ones by technical merit, not be their ability to write nice resume.

I don't remember the exact price, but when my company used them it was something in range of $100-500 / month.
