creating an application in order to import automatically dxf files from a website

We need a tool that imports automatically dxf files. This is the website: [login to view URL] There are several Product groups like * Furniture & door handles * Furtiture, Kitchen . . . * Architectural . . . The sub category for Furniture & door handles are Furniture Handles & Knobs Door Handles Window Handles Security Fittings The first article is "100.27.992 - Handle zi.chr.pol. 238x27mm " (see image) The file format is always "dwg 2010". I need from each article of each mentioned group one 3D-dwg file and three 2D-dwg files from front, top/above, left side. After all files from all categories and their sub-categories are downloaded, the dwg files must be imported to a cad system. This is simple, as there is a batch import for dwg files, so you can import hundreds of files directly. You will get a 30-day-trial-version of the cad software. You need about 4 GB RAM and 1 GB graphic memory for the cad software. We need for each sub category (like Furniture Handles & Knobs Door Handles Window Handles Security Fittings) a file with the symbols. The sub category like Furniture Handles & Knobs for example has 3172 results. Please make a quote for whole work including all dwg files for all categories from Furniture & door handles till Tools and Consumables.
