Content Rotation Script -- BetaTesters needed

I got myself into a jam when I bought a PHP rotation script and it wouldn't install, so I hired someone to install it. He found that parts were missing, coding was sloppy and he couldn't make it work either. So I modified his contract and asked him to make me a PHP script that worked for relatively easily randomly rotated "ad" content (or content generally) on a web page with a single URL. That is, if you advertise (elsewhere) to visit bbllaahhblah.com/bigsale.php you can have varied content for different products in the "bigsale.php" page because the script will (randomly) choose to rotate content of the type and in the place that you choose. (It doesn't have to be just ads, it can be salescopy A, B or C, or graphics A, B, C, D, E, etc. and works within the page you set up.

I need about 15 or 20 people to try this out as evaluators/betatesters to tell me:
A) is it in useable condition now, or does it need
i) better documentation
ii) better installation script
iii) add missing functionality (be reasonable, we don't need it to pick up your dry cleaning and wash the cat)
B) WHAT specifically needs to be clarified in documentation (if anything)
C) what do you think this is "worth"? Is is just a giveaway lead-in to future offers, or a $7 product, or a $49 product?

BTW, the script not only shows the content but also logs which content has been shown and how often.

Please email me at paymaster@winfotech.com to request a copy of the beta version of the script (no charge) and tell me why you should be one of my beta testers.

I don't know enough about PHP to offer much help or support for this script, but the author/coder says he'll support the script anywhere for anyone for $$ (he's not terribly expensive, and this is not just a ploy to get him work, I really want this to be a viable product).

And, yes, you get to keep the script and use it if you want (no resale or redistribution of beta software allowed).

Thanks
