Competent PHP Coder for OScommerce Programming

Hello, I'm running osCommerce v2.3.3 software along with Header Tags SEO module.  I have a few problems that all need to be resolved by a COMPETENT PHP PROGRAMMER. I have some problems with the way my URLs are being displayed in the browser and also being indexed by search engines. -Example, Google is indexing: [login to view URL] -But instead it should be indexing: [login to view URL] I have two versions of my site:  - a regular desktop version: [login to view URL] <[login to view URL]> - and a mobile only version: [login to view URL] A. I want to eliminate [login to view URL] & ?[login to view URL] from ALL of my pages. so the only thing desktop users sees is: [login to view URL] <[login to view URL]> and for mobile: [login to view URL] <[login to view URL]> B. If you use a desktop computer and visit this mobile URL [login to view URL] you will be redirected to [login to view URL] . This is wrong and causing google to index the wrong pages.  This is occurring on hundreds of pages. C. The site should not use GET variables (?) anymore.  I want to completely eliminate ?a=b style GET variables from my website. All Url’s should end up being SEO friendly URLs with no GET variables. D. A former programmer setup some sort of bad cookie redirect variable to detect mobile visitors and redirect to the ?mobileview=true site.  This all needs to be corrected and removed.  As it is now, if a page is requested for the first time, sometimes the user is redirected to the login page where I believe a cookie is generated. Then if they refresh they will be shown the correct page since they now have the cookie.  This problem is causing serious search engine indexing problems as well as user navigation problems.  Basically the correct way to do this is via detecting the mobile browser, redirect to the correct place and set a session variable or cookie all in one page load.
