Website Development with Google Checkout Integration

We are looking for a skilled PHP / MySQL developer to assist in the production of a Google Checkout payment shopping cart website for our VoIP service. The completed site will have the following functionality. -> Each customer will have a username and password to log into the payment area -> Within this password protected area the system will display various information about the customers bill, all accessible via our already established VoIP PHP API (example working code will be given) so the coder will have to be able to manipulate strings and arrays, again example code will be given. -> Will display customers credit balance from the API -> Will store and offer for download customers paid bills and invoices. These will have to be generated in PDF format in real time from data abstracted from a MySQL table. -> Have the facility to accept payment from customers using their credit / debit cards and topup their credit in our system via a PHP API which we already have in place. For example, customer wants to add £20UK Pounds to their account. They login, check their balance and type into a box how much they would like to add. The system then authenticates the payment through google checkout and if the transaction is succesful then it will open a URL pointing to a PHP with variables to add the credit into our platform. ## Deliverables The main requirement for this project is for the google checkout integration as most of the other work has been done and the customers call records etc are accessible via the existing API and will be easy to extract. We also need the new site to be graphically designed as it currently has no design. This design must be consistent with our current simple company branding. The winning bidder will be a competent PHP and Mysql developer and will be able to demonstrate work they have already produced using their own resources and without templates. They must also have very good design skills and be able to illustrate and design new ideas effectively using a good design package such as Photoshop or Paintshop Pro. All bidders must show work they have already completed in the form of a list of URL's. All bidders must have a good command of English and be able to demonstrate good communications during the bidding process. All bidders must also have an Internet connection capable of supporting a normal VoIP telephone call such as Skype as the winning bidder will be asked to install X-Lite VoIP software on their PC and they will be given an internal telephone extension on our telephone system for any questions backwards a forwards as historically we have spent too much time on MSN and Yahoo messenger. Only serious bidders will be considered and due to the high number of replies we will receive to this bid we cannot reply to all. Many thanks for your consideration.
