A number of my customers have asked if i could integrate Google Checkout?? Its not available here in the UK

Does anyone know of a alternative, other than paymernt gateways, that i could use.

What i want to do is add a bit of personalisation for each individual sellers with my sites logo and sale verification and etc. And then they in turn can add there own personalization so that the invoice relates to them and my sites sale.

thanks
