Build a simple Flash Shopping Cart System

This project should be very simple for a seasoned flash developer. We need a skinnable and editable flash cart to be used with Paypal website pro, templates are fine, as long as we can custom design the features and it works internally, meaning without redirecting to the paypal site. Our budget is tight, I obviously do expect it done for 50.00, but hopefully around 150 - 200 We will need the FLA file and any others to edit and would be nice to recieve instructions on how to add/remove products.
