78231 PHP/MySQL/Mod_Rewrite

We have a complex information site created by php/mysql and mod_rewrite for the URLs. Our infomation site lists a few stores with information on them. Each store generates (through php) it's own static page and it's own title, meta tags & h1 headings. We would like to have 4 additional sites. They would all basically have the same content. They should pull all the info from our existing database. But the design, layout, file names, and some universal text (including title, meta tags & h1 headings) would be different for each of them. I will email you with the URL of our existing site before choosing a bid for final confirmation that this project is for you. If you don't have experience and thorough knowledge of php, mysql, mod_rewrite, 301 redirects & unix server knowledge please do NOT bid on this project. Please indicate in your comments if you can do the design too. If yes, please indicate how much extra you will charge for design. I'm in EST time zone. When bidding on this project please indicate in what time zone you're in.
