I never managed to know how to pronounce the name of the ITcompany "Comarch"
"Computer Architecture" I imagine, thus "kom-ark".
There is a trend to pronounce anything not polish the english way.
Most of Polish would say "H and M" instead of proper german "H und M". (H&M clothing stores)
Don't ask me where does it come from - even me catched myself pronouncing "TVN Style" english way not polish as I should more likely;)
Name+Consulting should do.
Especially when your surname sounds foreign.
Jan Kowalski Consulting sounds funny for me.
But... Bruno Schultz Consulting seems to be right :)
