Why would you want to pay Visa's scam register fee and have a 1% Cb ratio?
Go with European corp in the UK unless you want to go offshore. If you want to offshore i think Gibraltar would be the best bet.
In the Eu you will enjoy a 2% Cb ratio and no Visa Fees whatsoever!
Cost like $250 to make the corp and 0 to signup with ccbill and Ibill EU.
