Copy from one store to another

Hello, I need a someone to help me make a program that can take the products from one website(not mine), and then upload those products into my joomla site 1.0 which runs with virtuemart. When it uploads, it should add about around 30% on each product, and add some information about each product given by me. Also I want the program to add a border + little text on each product picture. Same text and border on all pictures. Then it should be able to do this twice a week, remove products that the original store has removed, and add products that has been added by the original store. The store has about 4-5000 products. The original store from where i will take the products is this one: http://www.modelissimo.de/Onlineshop...ontinue+++++++ I have one programmer i often use who was suppose to do this for me, but something has come up for him and he won't have the time to make it for me. So I hope to find a great one here that I can perhaps use more in the future!
