i need to have a script updated from php4 to php5.x.x - repost

I have an open source php4 script that i would like to brought current with php5 and if needed and possible shell for security. there will be a few modifications to the script as well just to enhance it a little and make it more user friendly. for what ever reason this project was dropped and it's still one of the better ones available and was on the right track with out all the newer bs. please read info this and additional links as well for a more comprehensive detailed list and what we are trying to do. this will not start fast and after bids are reviewed it will be at least 2-4 weeks before starting the process. thanks and if you have any questions let me know.
