Listen to the man ppl. As Corey said been in US u have loads of options. It is just my opinion but i think its abit stupide to apply to some 3PP or Merchant account provider that is supposed to work with international customers.
1. You are doing more then 1 thousend a month.
2. Lots of horror stories about 3PP that got shut down by VISA/MC regulations and ran away with money.
3. Very high discount and transaction rates compared to a TRUE United States merchant account.
You should cosider WTH offer by CDGCommerce or Merchantaccounts4less. Alot of active ppl on these forums applyed with them and are happy.
With a true merchant account u will end up in less fees paid and less risk of losing money.
A few other benefits with a merchant account, you usually get your money a lot quicker with a merchant account & there is no need to call the processor or wait a few weeks to get your money. Plus your name will appear on the CC statement.
Do your due diligence and compare a few processors and 3PPs to see what might suit your business model.
