Worldpay provide a complete solution, secure payment page, card authorisation and transfer to your account but you're looking at something like ?300, not sure about setup fees as I've not looked at their service for a long time.
If you've got your own merchant account with a bank (could be ?200+ per year to run) then you can have an account with protx.com (?20pm) which just handles the online authorisation of the card and batch processing each night of your credit cards. |
