Simple PHP job, quick project for some easy money

I have a fairly simple website that needs some PHP programming done on it to finish it. A lot of the structure, such as stylesheets, HTML, the site database, site layout, etc. are already done, but I need someone to build certain elements in PHP because I'm only a beginner at PHP and don't have to time to learn more as quickly as I'd like to. To finish my site, I need the following in PHP: user authentication system, member area/personalized member page, database search/retrieval/manipulation, and a couple of other small odds and ends. In addition, I currently have a feedback form set up that uses PHP to send feedback email to my email, but it's buggy and I need help fixing it. Knowledge of Javascript is also required. I will provide detailed documentation on exactly how to complete the project to the winning bidder, and will explain how the site is currently laid out. It shouldn't take long and isn't difficult. This should be a quick project for some easy money. My only stipulation is that the coder must put detailed comments into his code, so that I can study it and become familiar with it later.
