Screen Scraper/ Web Crawler

I am looking to have a website spider/data crawler made or tailored so that will allow me to gather product information from other sites to put into my database. I've been playing around with a product called screen-scraper which has a free basic edition, but I'm not patient enough to set it up. If you would like to build something or use another free product that would work as well. If you think you can help me out, I am looking to gather data from women's clothing retailers in the following parameters: category (dresses, shirts, etc.) title description details price color material sizes features photos I would like the data put into a spreadsheet. Sites I would like to do a test crawl on are: asos forever21 delia's Please include in your bid what it would cost to customize for additional websites in the future. Thanks.
