Drupal Module Modification (PHP)

I have a website that runs the drupal content management system (cvs version). I already have the code for an ecommerce system that plugs into the site as a drupal module. But I need it modified. - The user enters the domain they require into a search box, should be able to do bulk search. - it checks the formatting of the domain to make sure it's correct (eg. A-Z, 0-9, -) removes invalid characters. - And then checks my mysql database to see if it's available. - If it is the user can then ad the domain to their ecommerce shopping cart(already coded into the ecommerce module) by choosing how many years they would like to register the domain for, discount given for longer rego. - If the domain is 1, 2, 3, or 4 characters it will cost more, set price. - If there is already an entry in the database for a domain it will check a field to see if it's for sale and if so display the domain as if it's for registration for the higher cost. - If not available the user is told and the search box is displayed. The user can now check out. - Again make sure all domains are available and tell the user if not. - Once paypal payment is made it must automatically add the domain to the database with the users ID, when it expires, and the yearly cost once it expires. The users shopping cart should also show each domain and how many years has been selected (it currently shows the quantity selected and still should but not when a domain is selected) when a user checks their shopping cart they should be able to modify how many years the domain will be registered for (just like they currently can with the quantity) They should also have a page that displays their current domains and allows them to check the expiry date, transfer domains, and renew each domain.
