Best experience for short term project freelance translators

If the part of project is short time, what is the best way to translate it? It’s a 1 time maybe 10-15 hours task. Should I go for some vendor agency or better to hire a freelance guy? If the 2nd option, where to find it? I know few groups in Facebook, but it’s not the best way as for me.

looks like this one is similar to your question

Well, yes, you have Facebook, Proz, some other freelance websites. Also agencies in Crowdin works fine.
