Data Mining - Data Scraping - Plumbing Supply

I own a plumbing supply website and we are moving to 3d cart. Need entire manufacturer product lines in a csv file format for 3d cart upload or similar format. Need several criteria met as well as image download in name of product/sku. csv file will need manufacturer sku, item name, item description, long item description/detailed info (including basic html), retail price & weight. Manufacturers include american standard, grohe, kohler, moen and more. I am not sure what I am willing to pay until I get some quotes. sample extraction sites will be provided upon request. you will need to determine easiest place the data is available. Have you performed similar work before? If so, please reply. Feel free to share the software and method in your response.
