basecamp api job with whmcs - repost

Hi i need a module and/or plugin which does this: When a customer buys a product from a certain category via our website which uses whmcs the user data (all available user data) gets put in basecamp and a project is created for that specific client in basecamp using the companyname of the client as projectname. The project must use a basecamp project template to set the project up. A bonus would be that if a project is closed whmcs gets noticed and that whmcs then sents the invoice to the client ( we dont use proforma) The module and/or plugin needs to have a settings page where all needed data can be given. it should use whmcs hooks or api and basecamp api to do the magic, NO database manipulation, no other way! Job will be done when all works well as specified above Time tracker must be used all rights will be ours
