I'm a native English speaker, and I've lived in Germany in the past. I'm a member of the Chartered Institute of Linguists and have just taken the Diploma in Translation exam (I'm still waiting for the results). I've had good feedback from test translations with particular praise for my natural style.
Normally I would charge $0.10 per word, but since you don't know me and I've never done any work for you before, I'll reduce it to $0.08 for this job.
