Program to monitor a certain area.

I am looking for a programmer to create a certain clicking and monitoring program. It will have to do the following task: 1- Click a certain pixel that I choose on screen. 2-Monitor a certain area on a page that I choose. 3-Send an e-mail to one e-mail address when the selected area has different colors. This program will always be running on my computer to track a certain web page. Please let me know your budget and how soon you can deliver.
