Data Mining/Scrapping App

Hello, The budget I have selected is just as it is mandatory. You are free to give me your best price. If you can develop an efficient data mining/scrapping application, then we would like to hear from you. We would like to download nearly 14000 products from a particular website. And we need an automated process for doing this. The application needs to have these features 1. Copy all product information such as brand, category, price and any other information related to the product. 2. Download Thumbnail & Associated enlarged images. 3. Build up a proper CSV product data base based on the structure we provide. 4. Should be light, fast and run error free. We need this done fast and at reasonable price. Please submit your profile with similar examples. We will share the name of the website with shortlisted candidates. Happy Bidding.
