251856 Rewrite website using Zen Cart

I need to have an existing website rewritten from Miva Merchant to Zen Cart. I want the same basic design. You DO NOT need to know Miva Merchant to do this project, I am looking for a Zen-Cart expert. Things I need to have done. 1. I would like to have the design done with standard Zen Cart template logic utilizing css where ever possible. 2. I would like the internal links to utilize the standard Zen Cart logic. 3. I need to understand exactly what is modified and how to do it so that I can modify the site in the future. I would like documentation for each major procedure on file affected and code changes required. 4. I would like the development done on a different site from the actual live site and then have it ported to the actual site when it is complete to keep the down time to a minimum. I could create the actual site on my server and then just change the DNS entries to point to the correct server when the site is finished. I'm not sure this would work though. 5. I want to have the coupon module installed that will work with affiliate programs so that affiliates can have coupon codes tracked also. 6. I want to have the affiliate script PostAffiliatePro integrated into the site. Using Paypal IPN. 7. Need it to be configured for Paypal IPN. 8. I want a sign up form on the home page, this will need to write the emails to a mysql table. 9. I would like the URL's to be SEO friendly. 10. I would like to control the meta tags and page titles for each page. 11. I want the product descriptions to be similar in appearance to existing site but I want to control the price inside Zen-cart, current site has the prices as part of the product image. website is www. bathlab .com
