Translation of bounty in Spanish

I would like to give you a proofreader's project. Proof reading sample sentences that were entered into the dictionary by our users. It is a very tough project and needs a lot of discipline and patience.
Thank you for your answer. Your correction in Russian has helped me. I'm glad to have found a Russian Vocabulix friend with Russian as the mother tongue. I will help you in Spanish, OK?
Today I have a lot of time because I've just returned from a 3 day vacation. For how long have you been teaching German? For about 3 years I have been studying Spanish mostly alone, with books and stuff.
