Homepage Image Slideshow - JS Programming Needed

Hello, We want to add an image slideshow to our Homepage (4 slides total). Here is our current homepage with a static image: [login to view URL] And we want our image slideshow to look like this (i.e. we want it to scroll vertically, with up/down arrows to the right of the image): [login to view URL] However, we want the background in our slideshow to stay FIXED, while only the content scrolls on top of it. I've attached a PSD that contains the 4 slide designs we want to use. I expect you to slice each slide to minimize its loading time. The attached zip file also contains all of the HTML/CSS/JS/Images for our Homepage, so you can make sure your slideshow looks and works correctly in its final environment. We are looking to start work immediately, so please submit a FIXED BID for the project. We will choose a winner based on your vWorker ranking and cost. Thanks, and good luck.
