Copying data from different website and add it in one website!

Hello, we are looking for a professional PHP&MySQL and Javascript coder who is familiar with PRESTASHOP. We want to run a local catalog of products, our clients are different online stores, and we want to add products from each store in one Database (our catalog). Here is what we need: ------------------------------------------------------------------------------------------------------------------------------------- Our catalog is running on Prestashop, using Agile modules for multi-vandor. So we need some SCRIPT that will scan a specific URL and grab all required data like: images, product name, product code, price, old price, new price, description, items in stock. And all this info must be saved under a specific category which will be indicated at the beginning of scanning. We need this to work fast, with minimum human interaction. in order to explain this in practice, let's make a example: 1. in our catalog we have entered those categories: - Electronics (id=2) -- TV (id=3) -- Computers (id=4) 2. we have registered using Agile module a new store "Store number 1" it's ID is 21. 3. I want to scan all products from this URL: [login to view URL] and save them in my catalog under category id=3 and where shop id = 21 so, the Script must copy all info for each product and save it in our database. Maybe opening each product will be required... we know it is a huge work, therefore we don't know how much this can cost. and even if it is possible to establish. So, we are looking for any offers! Please ask any questions about this!
