changes required for a php based website scrapper

I have a php based scrapper file that scraps products from my manufacturers website and inserts them into my oscommerce site database. The scrapper script has some filters in it so you can scrap specific categories from my manufacturers website. The manufacturers website is not an oscommerce site. I have imported several categories and products in January this year but im now finding the manufacturers can no longer supply many products. I need 2 changes to the script. 1. this error shows sometimes: "Error. image file not found by regexp in ...." 2. add "sorry sold out" to product info page if item is no longer found on the manufacturers site and is in our database. I will pay $30 to anyone who can make these 2 changes.
