I know, there are not a few colleagues who have tooted in this horn many times before, yet it cannot be stressed often enough: Good translations are not cheap. And if they are cheap, you should seriously question whether they truly are good. And that’s not even factoring in the turnaround time factor.
(I’d like to point out, that “cheap” here does not mean “for peanuts”!)
Masahura Hayataki has written a very good article on the topic, and I highly recommend reading about the “3 reasons why good translation is expensive and it’s totally worth it“.
