Integrating an Online Shop into Gallery 1

Hi,

This is for anybody/company with experience at customising Gallery 1. I have a client who has a version of Gallery 1 running on their web server for sometime which is solely used for his clients to login and view their wedding photographs online (they then contact him via phone to order prints). He wants to be able to allow users to buy prints online through Gallery and then pay for them using Secure Pay (http://www.securepay.com/) as their payment processor (they already have a Internet Merchant Account. Developing such an add-on is way beyound my skills so I thought I'd come on here and ask about to see if anybody would be willing to develop such an add-on.

If anyone has had previous experience of developing such a solution then please get in contact with me and we can discuss the project, costs, timescales etc in more detail.

Any help/suggestions would be greatly appreciated. My clients is really keen to get this feature added to his site.

I hope this is in the right forum!

Thanks

James
