Web shopping page improvement

I have developed a beta shopping page for my web site which I want further improvement to add some dynamic feature on the page. You can see this beta page on [login to view URL] The change I want are as follow: 1) Style selection by clicking on the style image. Such selection could be of blouse, jacket, tee shirt, etc. Based on the selected style the page will dynamically display appropriated recommended color and other available color and available size/price information in the size area. Without color selection the size/price most be information only not selectable. 2) Color selection by clicking on one of the color image. Base on the color selected the page will dynamically display appropriated available size/price information in the size area for that color selected. If the size for the selected style/color is not available for sale that size must not allow to be selected and indicate sold out. If the size is not available for that style Do Not display the size/price information. No database here all the availability information will be in hidden forms. I use server side include to pass data to the pages. 3) Size selection by clicking on one of the size image. 4) Modify my script "Addupdate.js" to reflect the selections before submit. This part of the work can be done by you or my self. Please indicate your preference in your bid. Above work will replace my color selection and size selection pull down options. The work to be done with javascript, and hidden forms. No proprietary codes/scripts to be used without first cleared with me. Use of public domain javascripts or code is acceptable. I reserve the right to modify all the work. I have codified many data and standardized all file names to facilitate dynamic coding. Design have 3 digit numeric code. Shirt style have 2 numeric code: 10 - sweatshirt; 12 - jacket; 20 - tee shirt; 40 - tank top; 55 - blouse. Color have 2 alpha code: BK - black, BN - brown, CA - cardinal; GO - gold; ... etc. Size have 2 numeric code: 80 - extra small; 81 - small; 82 - medium; 83 - large; 84 - XL; 85 - 1X; 86 - 2X; 87 - 3X. I will do all the graphic and image work my self. I prefer implement changes in small scales that allow me to see if the work done is exactly what I want. That way we don't waste your time or mine. Your thought on implementation may help me decide the wining bidder. Feel free to ask if you want more information. Happy bidding David
