Let me know more details about what exactly you need done because you were kind of vague in this post (for example is the purchase page just links to paypal or a whole e-commerce solution, etc.). Depending on the further details, I may or may not be able to help you out at the present time due to other things I am working on at the moment.

I am experienced with all that you asked, graduated from college for web design (usually outsource as I prefer coding), development and maintenance and am presently working as a web/flash developer for one of the largest and most successful banks.
