Search workshop or V8 hobbyist in the Ruhr area

Hello, everybody.
for the second time I have a V8 and this against my wife's sake.
I'm hanging on to the vehicle, but my wife's been keeping a good deal of money.
My problem: My V8 is close to the Tüv and it's 2 points that make me worry, first the climate compressor, which is now very loud. I have a replacement, which has to be completely overhauled but the installation is still missing. A little more violent is the steering that loses oil, according to the workshop the steering gear and this means a lot of work.
For this I have not yet a replacement but the installation is probably very expensive.
==References====External links== I am looking for a workshop or an experienced V8 team to keep the costs manageable.
I am in Wesel County and I am grateful for every answer.
Oh, I'm a trained baker and I don't know much about car.
MfG Carsten
