Looking for an experience php coder to debug a website

Hi, we have a tailed made website design in php. The previous coder was unable to resolved all bugs found on the site. Some of the code are badly written so it's difficult to trace back to the problem. We have manage to resolve most of the problem with the help of a French coder. But he had to leave the project for other work. So we are looking for somebody to finish this project urgently. attached you will find the website URL and all existing bugs. Mostly with paypal modules payment and email alerts issues. If you are an experience coder kindly bid on this project.
