This system will have similar functionality to price grabber(like [Trademark masked].com but not so complicated), but will not be as large as price grabber. (it will probably only search through about 48 websites)
Screen scrap/data mine about 48 websites for prices for about 25 categrories of products (would like to be able to add/remove both websites and products). Note - not all websites have all products. Write prices to a MySQL database.
See attched requirement
The budget could be raised a bit.
And the sites I am monitoring is not listed on either price grabber or other sites like shopping.com dealtime.cm, it's about in game virtual currency price.
