Hi.
The project sounds really clear and streight.
I have fresh experience with XML service, both SOAP and no-SOAP(aka REST), even I think this is some kind of fashion to use XML because I see and do more and more projects on it.
Interesting reading about SOAP. However, I perfer using cURL instead if the built-in PHP library. Hope this is not a problem.
If all goes smooth, I will try to finish the project even on 13th midnight so I can withdraw the money this week.
My weak side is graphic design. I hope you don't want me to create some fancy design on the forms.
Greetings,
George
