Custom PHP / MySQL site for Sales Force Management

I need an experienced programmer that can write clean/commented code for a new business venture. You must be easy to contact and talk to by email and/or skype. The job is to build a custom site incorporating: * MySQL as the backend database. I can provide a basic database layout to show you what I am envisioning, but you will expand on my layout and setup the actual tables. * A registration / login portal * A credit card processing section incorporating SSL to allow field salesreps to process customer payments securely. * A basic CRM (customer relationship manager) to allow field reps to track leads, accounts, contact details and 'touches' with clients. I am looking to have the site written in PHP 5 using an MVC framework, preferably Zend or Symphony.
