301 Rewrites for Linux PHP Server

I have another website that will be moving to a Linux server. On this project I'm looking for very experienced coder to implement a custom 404 page to handle 301 rewrite rules. I will provide old url and new urls for you as well as the old productid's along with the corresonding new product id's in database table so that your work is easier and can progress more quickly. You will be responsible for writing the rewrite rules and making suggestions as to how best to implement the actual rewrite in an efficient manner. Must have very solid experience with url rewrites and be able to write rules that do not run into loops etc. Please respond with a descripion of your experience in using rewrites. Also let me know how quickly you can start this project. Looking to work with someone that has good command of the English language and who can start right away. Must be available on skype or Gchat during project so that I can assist you. Thank you for your interest.
