I'm looking to start an online business can anyone provide info?

I'm looking to start an online video game business.I'm trying to find legit suppliers .I did a lot of searching the web but all I can find is so called "wholesale suppliers" which are mostly (if not all) middlemen.Worldwidebrands,salehoo,dobra,… to name a few say they have true wholesale prices but do not! all they are are just some list.Can anyone point me in the right direction? Maybe some forum,a particular company,or just a place to find more info?
