If you are looking for someone to translate your rules from english to german, ask me, I´ve done this before.
I usually translate the rules from english to german and after this, a proofreader is correcting my mistakes to have a perfect product at the end. If you have no one to proofread my translations, I can provide someone. I´m not doing this for free, also the proofreader wants to have something for his/her work.
But don´t worry, I´m no professional and If you could send me a game or two and/or a small amount of money, I could be the right person for you.
