486461 cURL function with database update and php knowledge

Hello to all, I'm looking for an excellent programmer who can complete the following task within the next few days. I have a database that has 500k+ products from many stores: Dell newegg bestbuy etc.. In this database you will find a name, description, url, price, salesprice. Your Job: to create a cURL function that will crawl these url's to update the sales price. example newegg store: My database records this item to be $89.99, with this url. While the price is correct the old price isn't there so users will not be able to tell if this is on sale. [login to view URL] Let's take another example. A product x passes through the cronjob you will create and there is no old price. If the price is different then the one we have on the database, the item should be marked on sale with a timestamp. Let's take an HP example: My product says $1,450.99 now check the url: [login to view URL] Now you see two prices have to be changed. the salesprice and the price Price: $1,284.99 - instant Rebate: $150 Salesprice: $1,134.99 You must be able to complete all this with ease and knowledge as we have over 20 stores at the moment. And you need to make sure you check in details each store. another example: this product is $9.99 on my website. I can see list price of $11.99 on their website.
