87782 Site Crawlers

We require a site crawler that will download the information to a CSV file on our server. We have at least 20 fields we need separating with some "smart" working of the script to do the separating. For example DATA= BIKEBOY45RIDGERIDER CSV= MAKER"BIKEBOY", MODEL"45RIDGERIDER" BUT ALSO DATA= TRAILER/SNOOP CSV= MAKER"TRAILER", MODEL"SNOOP" and so on... Please let us know if your company has previously done this kind of work and provide us with verbal examples. How does your company go about doing this work? Can one crawler that is working for our site download from several different sites? Are there any limits to that and what problems may we face? How "smart" can you make your script ? What language? We also require getting the images that go with associated products. So they can be linked in OUR database from our site. We have a lot of this kind of work available so a comprehensive message board post would suit you best before I choose. Best Regards
