Q/A - testing game company start-up

I wanted to set up a company in my region that will specialize in game testing (Q/A, bug tracking). However, I have a limited experience in that field

Then this sounds like a mistake. At the very least, buy a couple of books on game QA. Better yet, get a job doing QA (preferably at the type of company you want to build). Find out firsthand what they do. Then, while writing your business plan, start networking like crazy. You absolutely must attend GDC, coming up this March. And join the local IGDA chapter. If there isn't one, start one. If there is one but it's dormant, take it over and kickstart it. And start registering for every conference and tradeshow you can find.

Game Development Essentials: Game Testing & QA (Levy)
Game Testing All In One (Schultz, Bryant)

BTW, this is a Business question, not a Production question, so I'm moving this.

Hi,
thanks a lot for your advices and readings.
I'll start reading and documenting, I'll check companies specialized in that area or at least try working in their Q/A department.

thank you again.
