Dealextreme webscrape to prestashop or shopping cart system

Hi, I would need the help of an individual that can utilize data mining to web scrape dealextreme's website and to transfer it's products onto my website on a daily basis. This includes its categories / product pictures without watermarks (possible?) and also to update contents (SKU?) to which products have stock and which are out of stock to reflect on my website. I need this to be an automated system whereby I do not have to ask for it everyday but it is auto, kind like a turnkey solution. If possible the uploading of its products are near auto as well or at least in CSV format (easy populate?) where I can amend prices. I have previous websites that are on prestashop and oscommerce but I would require your input to tell me in your experience, which is better to use. I am open to utlize other cart systems as well i.e magento, zencart, xcart etc. Please use what you are comfortable with even if it is your own ecommerce system BUT the backend has to be user friendly. I am tech savvy but not a programmer hence I need your expertise to build this online shop. Also I need this system to be SEO friendly and can incorporate social media as well if not already in the shopping cart system. I believe this has been done before but if you are confident, please bid!
