Javascript/html coder required for simple changes/config work

I have with me a javascript shopping cart- it shows the items on screen, and when user wants to checkout, it sends the data to paypal. I want you to modify this so that it shows items from my FastSpring account([login to view URL] is a paypal alternative) and after user has made his selection, forwards the information to FastSpring for further processing (just like it is done at PayPal). I have with me a HTML template for blogger- you have to create/add widgets for the shopping cart into the blogger template. The final shop page should look like the original blogger template. Also one small task is that I have the HTML/CSS version of the blogger template-it has an image slider in it- I want you to implement the image slider in the existing blogger template... You can also visit [login to view URL] and [login to view URL] for more details on how to complete this project. Note- No secure info should be made available to hackers etc....The shopping cart should safely forward checkout to the FastSpring website Simple work for a good javascript coder.
