tax time-oh crap...

ok, i have never filed taxes overseas, perhaps my situation is a bit different from most others on here.
i work for an american company, paid in american dollars (which maybe is why i feel like im broke.) and paying american taxes. i will not be back to north america before filing time, so i guess my question is, does anyone know of an accountant familiar with american tax laws here in germany? i need to understand what i can write off, and i would prefer to pay someone than go through the regular hair pulling-i have lost enough already
