AI (artificial intelligence) Price Checker

We are looking to create a script in Perl, Python or PHP that would go to any online store product page we throw at it, and be smart enough to gran the price of the product on the page. For instance, a user saved a product from Amazon or [login to view URL], the script would find the price on the page, we would store it in our database and do a price check periodically to make sure the price is the same.? We are not looking for build a script that relies on regular expressions, we do understand that the script could not get the price right all time, but it should most of the time. The script could be run every day on a CRON job, access the product page, crawl its content to extract the closest match to the product price, retail or sale price. We are looking for someone with AI experience and strong PHP/Perl skills. Once again, we are NOT looking to build a script that relies on regex, the script has to be able to able to extract the closest/best match of the product price from any online store. ## Deliverables Similar site: [login to view URL]
