Magento Cart

I have created a simple Magento Cart Website, I need the following: 1. Some Skinning work done using a couple of free themes we've have chosen. 2. I need products setup that will be both "download-able" as well as "shippable" from warehouse. 3. I need to sell CDs with "sampling" ability. the sampling should not take the user to another web-page. Item #2 above applies to the CDs. 4. We need PayPal "Standard" payment option setup and tested via "sandbox", then implemented for production. We have PayPal standard business account. 5. After PayPal payment is complete for a "download-able" item only, the item should be immediately available for download without manually creating an Invoice. 6. Bidder will be responsible for entering ~30 items from old website by visiting site and copy&paste. This will include 4 Cd albums and sample mp3s, several books with correspondence courses to accompany the book--may have to be setup as some sort of "grouped" item. 7. We will supply mock-up "Home" page and a CVS import file based on instructions from bidder. 8. 1 embedded video 9. I need this completed by 10/03/09. 10.I need 30 days support after project ends.
