New Version PHP Cart, Need Custom Coding

Hi, I'm looking for a skilled PHP and Javascipt Programmer who knows Smartypretty well, my cart is written in PHP with smarty. I have all the custom coding on my current store which has an olderversion of the cart in there. I know what files and location of thecustom coding for the most part in both old and new version of the cart. There are 7 parts for this project: 1. Price language changing, There are some languages that needschanging, such as in the tier pricing needs to show the actual price,catalog pages needs to show the lowest price instead of the highestprice, show "as low as" and "unit as low as", products with sets needto have "set of", the catalog pages needs to show the lowest pricinginstead of highest pricing. 2. Check box drop down for products with personalized tag such as here: [[login to view URL]][1] 3. Navigation needs to be reformated from: [login to view URL] to [login to view URL] 4. Session Saving - Right now the new cart is only saving someone'scart and info for only few hours, I need the session to be saved for atleast a few days. 5. Continue Shopping - on the cart page, continue shopping just goes tothe homepage, I need the button to go to the previous category page 6 Search algorithm - I had someone built a custom search algorithm inmy store, I need to transfer that over to the new cart. 7. 301 Mod Rewrite - the new URL structure is different. I need someone who's familiar with mod rewrite to write the custom 301redirects for me. Old URL: [login to view URL] New URL: [login to view URL] Need 301 all pages from the old cart to the new cart, matching eachcategory page and products page, text page and such. I have the custom coding for all 1-6 for the old cart for reference. I need someone to do #7 based on the structure of the URL. Thanks
