Tracking Unique Visitors, Your help could help us save a life Options

Okay, so the description is semi-dramatic, but it could in a way.
I'm a new user, btw.

The AHR group that I'm in (Assembly for Human Rights) is trying to create a Click2Donate type of page on our yet-to-be-created website/blog. The way it would work is that for every unique hit or click we get on a certain page in a twenty-four hour period, a sponsor would donate to our cause X amount of money. I need a way to reliably track these hits. I've already looked into just using the standard Web Stats that come in CPanel (Awstats, Webalizer), but I'd like something a little less complicated to present to a pending sponsor when asked, "How do we know how many clicks you're getting?" If anyone knows of a script or a preferrably free online service that could fill our need and could pass it on, I would be incredibly grateful.

We are trying to raise money for the situation in the western Sudanese region of Darfur. We plan on passing out cards with this project's url on it at our Darfur Awareness campaign on July 5. If you would like to help out in anyway, just spreading the word would make an impact.

Thank you all :)
