PHP script to automatically add some ads on a website

Hi, The Goal of the project is to add some ads on a big French website, including a picture for each ad. You probably must use Curl to achieve this project. The Website seems a little bit protected against this sort of script. The data of the ads should be in a text file or in a mysql table, as you want. There's a lot of mandatory fields. Optional fields are not a big problem, if mandatory fields works well, i should add them manually. Source code must be clean and commented. As i've been ripped off by the previous freelancer, i will be very strict and i'll only pay after intensive tests. Please add the word "france" in your bid, in order to know you read everything. I'll give you the website url in private. I'll be out for a week, so you'll have some time to try. I'll only choose someone when he show me something working well.
