Rewrite a script with works with xml feed data

I have a website which runs with a xml feed from an affiliate program. The script for that website runs on a xml feed, it takes the datea, puts it in the database and displays it on the website. There is also a load function for an update, which trows out all off the old data and puts in the new data, so then the site is updated. Now we want to switch to another affiliate program but thats another xml feed with other data, so it does not work with the script feed because of the wrong arrays and everything. Your job will be: I will give you the old script, your job will be rewriting the old script to an new one, which works good with the new xml feed which i will give to you also. I think for somebody with experience this will be an easy job: change the rows in the mysql database, change the arrays in the script, let it all communicate with each other and make it work properly. Let me know if you want to do this job for me I am still looking for someone to do this for me so let me know
