Hi!
Those works are usualy charged per word count, not hourly, whiech is abit unexpected. Please provide lot specifications, especially: total word cout (as is in teh English text), Industry the content relates to(if any),time-restraints(if any), samples of each of the files in question, for a close up assessment of quality and the required effort that would need to be put toward making the end result a successful and easy to read/nderstand text i Bulgarian, etc.
Regards,
Dobri
