Create Website Forms with Linkpoint API connection

We need to have 3 forms completed that have some basic fields as well as a selection list for different amounts + credit card information. We need to have this page just be submitted via POST for processing to another script (php). This script should send the credit card information to linkpoint and show a success or unsuccessful message. The script should also send an email with the information submitted formatted to a specific email account (without credit card information obviously). Alternative we can also store the submitted information in a mysql database table. Forms should have a simple but customizable validation of form fields. Code should be documented and tested before (we can test with our information the script with payment gateway information) Please contact us for any additional question.
