I spoke with SecureHosting last week (Jonathan Rodger) and who today has sent me this email.
We would be delighted to have this as a cart that supports the SH payment gateway. The shopping cart code would first have to be edited to include our gateway. If this is just a one-off and the cart is written in PHP then we could do this for you (for no charge). It might be a better idea though to get Webassist to put in a generic SH gateway module so that all future users have access to it. Do you know if this is something Webassist are happy to do? If so we can just send them the integration instructions.
I look forward to hearing from you.
Perhaps you can initiate some dialogue with the company which may benefit everyone!
I look forward to your thoughts.
