Goonx:
If you need a processor in addition to Verotel (and you do!!! *s*), get a Euro corp.
You can then deal with CCBillEU and any processor in the EU banking region. A basic corp (not Euro "offshore") costs less than any North American VISA fees and no VISA fees apply in Europe.
Check out eg.. a UK non resident company

Nominee dirs and a "presence" are other options. Tax exemption from all UK taxes is available and no chance of any withholding taxes applies as with US corps.
