Bamboo Invoice modifications - paypal + database integration

This small project contains 3 tasks: 1) I need a mysql / php programmer who is skilled in mysql databases to integrate Bamboo Invoice ([login to view URL]) with our existing sql database of existing customers (so we can use Bamboo to send invoices to our existing customers). 2) I also need a modification done on Bamboo so I can accept paypal payments from customers via their invoice (there is already a free mod released that can achieve this - I just need you to install it.) 3) I need some basic customisation of the layout of the system. E.g. put our logo on the header, match the colors to our company colors etc. I estimate the time would be spent: 80% on task 1, 10% on task 2, 10% on task 3. Budget is around $200-300 for this small project. Your bid will win if you can demonstrate an understanding of my requirements and propose a solution that makes sense from a technical viewpoint. Spam bids will be ignored. Previous experience with Bamboo or alternative invoicing software will be highly preferred.
