Seek native German speaker to tidy up machine translated video script

Hi, I've used a machine translation service to translate my English language original youtube transcript into German. The machine translation won't be perfect. I need a German speaker to tidy it up for me. I'm a fluent French speaker so I have already done the French version myself. It took me around 4 hours to tidy up. I estimate that 20% of the machine translation had to be changed/edited. I think the machine translation is a good starting point. It would have taken me at least 2 days, probably more, to do a translation without it. (Also, although very fluent in French I'm not a native speaker.)
