1 Hour JavaScript/PHP Job

I need someone who can spend an hour max today to help with a couple things on my website. The coder needs to be highly skilled in form validation using Javascript, PHP and mySQL. ## Deliverables Goto [login to view URL] Part 1: Click on Order, then select a racquet type. The user must select a String and a Tension. If they do not, then a message box will need to appear alerting them. Click Next Same goes for this Details page. All info needs to be filled in otherwise a messagebox appears. Part 2: Click Order and select a racquet type. I would like this page showing the String/Tension modified. When the user selects a string from the Drop Down box, I want an image to appear on the page. The image will be a picture of the string with details. If the user decides they don't want that string, they can select again and the image will automatically update as they flick through different strings. A new field in the mySQL database will need to be added for the image link, and the admin panel needs to be updated so when I add a new string I can add the link to the information too. I need this work done within an hour or 2. Ideally coder has MSN so questions can be answered immediately.
