Scrape website extract product date to create xml or csv feed with required info - repost

I need someone who knows how to properly "scrape" or extract product data from one site so I can easily create a datafeed to upload to my site. You can extract it as an xml content or whatever so long as the end result is a proper and complete spreadsheet I can use as a datafeed. Required fields needed : Product name, SKU/item number, Product price, product description, any size information or weight if included, link to the photo url and relevant product category. Will provide website in PM. Website requires a login to access which i will provide. We are authoried to access this website as a wholesaler however they do not provide a feed. There are probably over 500 products but I would be willing to break this down into smaller projects per certain categories. Please review site first to get an idea. I roughly counted 500 could be more though some products overlap each category
