CL program needed

This wont be too hard for the right person i want a program built that functions just like http://www.clextractor.com/ but in mine i want to have a search feature added that will search in the title for prices. another words i want to search for items and gather the emails to those ads by price. let me know what you can do for me. It also needs to be able to extract the url to the ad as well so when they respond to me that i can click the url and go to the item.
