Automatic submission of classified advertisement to site

I would like a PHP script wich gathers data from MySQL database and sends it to a certain free classifieds site (asp, .net based). The mechanism of the script: -it has to go through a MySQL database and send the new ads to the classifieds site automatically -it has to submit older ads again at a certain time (e.g. twice a day / if the ad is not displayed on the first page / etc., whatever works better) -it has to delete all the duplicate ads on the classifieds site What is important: -the target site is NOT in english -the target site is free to use and it's legal to submit as many ads as you like -if you bid please post how much time do you exactly need to complete the script -I will give you all the help to develop the script (with the language difficulties of the site, how it works, etc., everything you ask for) -I will give you a link to the site in PM
