German Speaker/Writer Required for Translating Data

Hi we require: *German Speaker required. I have a spreadsheet with approximately 3/4000 rows. i need titles and a few other attributes translating from English to German Titles must have an 80 Character limit (we can provide a formula to let you know if it is over 80 characters). there are more requirements like this but i will explain all and make the spreadsheet look as easy as possible. You have to prove that you are proficient in the languages above and English. No grammar or spelling errors allowed. The work is checked by a native speaker and payment is released upon approval. We have regular data every month which needs translating so we are hoping to find someone who offers the best quality and price for a long term deal.
