Single Page Payment Form - PHP

.. .. I'm looking for someone to create a single page payment form (with css, centered 70% screen) that can post payments to [login to view URL] and write out the user data to a flat file (pre-pended or one per customer is ok). Our NOC guys will make necessary changes to push the data to a secure SQL server before it goes up. This code is a redo to uncomplicate an eight year old interface. One of our main goals is to pretty it up and simplify what we have. This is going to read sloppy but I'll try to get it all into this edit box. Procedures to implement: Pre-color the background of the Fields, and do fields checking (javascript?) for abnormal / missing entries, auto-clear any "text" on entry into the fields. A live E-mail account check would be good, but is not a must have. The post to Authorize net needs open an secure (SSL) link, on return evaluate AZN's code for approval, declined, address mismatch street/zip, cvv mismatch. After eval, fork to display the user-correctable errors (try a different card, Insufficient funds, ect) in text - preferably on the same page, a consideration here is keeping the customers already entered data(probably not the CC data). On successful evaluation of the return (payment good) we must create an 8 character user ID and 8 char. password, this is not a customer option. Once the UID / PW pair is created, we send an https OR http post to another server to establish the account. The second server will return a result to evaluate, we need to keep the previous stuff so we can show the customer a receipt along with his account UID/PW, write the data to the file. We need then format that servers return string into a "success" page for the customer. If it fails we then send email (windows machine E-mail app, AND unix need to be supported) to an admin@ address. A "thank you" email goes to the customer, and "order placed" details to a sales@ email address. Form fields. All fields are required. NO popup boxes. Bring the errors foward on the form or return the page with colored + underlined text, once per item. (Generate an Invoice or Order ID #) Invoice # (required) First Name (required) Last Name (required) Billing Address1 (required) Billing Address2 City (required) State (required) Zip (required) Phone Number Email (required) country selector? Break for logos & Authorize Net Seal and SSL Seal Credit Card Type (MC/Visa/Discover) (required) Credit Card # Credit Card Expiration Credit Card CVV Code Three check boxes - user must tick to proceed. "I have read the terms" "I agree to agree" "One more important thing" Submit button. (Break) declare footer ------------ I set the price range $250 - $750, but honestly this can be done pretty quickly, be kind! :) Overall, the smaller presentation is better, use inline or external css, no specifics on colors other than the back face of the form fields. Thanks, Mark L. .. ..
