Hello I need a automatic bot to crawl or spider several different websites for classifieds ads. I then need the bot to copy the ads I need the bot to post the ads on my website script. This is my website so there will be full access to admin panel, no captcha code or any other type of security to deal with. The automatic bot must post text & pictures by location & category.. The bot must post most recent ad by date & not post ads with duplicate telephone numbers. Existing programs that will meet requirements are ok. Please serious & capable bidders only.
