Hi, I recently finished crawler project here at freelancer.com. My crawler can crawl several web sites in parallel and can store received html to database table . This crawler has several parameters like politeness delay, crawled page count, number of parallel crawlers, list of domains to crawl, deep of crawling, etc. If you interested, please ping me, I can provide demo for you.
PS: if needed, I can easily modify some parts of this project for your needs.
Best regards,
Viktor
