Authorize.net Donation Page (2)

I was about to select the winning bidder on Scriptlance when Freelancer took over. My apologies to any of the bidders. I will be choosing a bidder much more quickly this time, because the project deadline is approaching. We would like a donation page with these features: - Both one time and monthly recurring donations - Remembers donors, name, address, city, state, zip, email, phone number from previous donations (stored in cookie?) - Good form error checking We like the functionality of this donation page: [login to view URL] More on functionality: One the first visit to the donation page, the donor would fill in their name, address, etc. and credit card. On the second visit, only the form fields to fill in the credit card # and exp date would display. "Welcome Back, DONORNAME" would appear instead of the personal info form fields. There would be a link, "Click Here if you are not DONORNAME", which would display the original empty form. Preferably, all this would be achieved using AJAX, so that the page would not be reloaded when the "Click Here if you are not DONORNAME", link was selected. The bidder who responds with a clear understanding of how this additional functionality would work will win the bid. The Payment Gateway is Authorize.net. We'd prefer coding to be in PHP, Javascript, CSS, html. Let me know if you have any questions.
