Processing an international credit card.  What are the conversion fees for my client in U.K.?

I won't have too much insight here unfortunately, as that will be decided by your customer's bank. 

Your transactions can only be processed in USD (or CAD, for a Canadian account) and the currency conversion and any fees associated will be determined by the card-issuing bank. Hope that helps.
