Hello guys.
Sorry for English, but I'm not yet good with Czech 

Some time ago my clutch died and I went to my colleges family to fix it. They changed clutch, but after putting engine back it is not working properly anymore. Then I tried few more places, but nobody have experience with this car 
 Now engine is not working at all ( looks like only 1 or 2 cylinders are working ) and there are some more issues.
Can someone suggest me some good guy in Brno ( or close ) who could check my car and fix it? I'm thinking now about BMW Mini center, but I know that they will take a LOT money for job and details. 
I have year '95 1.3i Mini and I really love my car. I already went to Portugal, UK and Czech Republic ( from Latvia ) and I would like to continue my journey 

Thanks in advance,
Mike
