Script for Squidoo Lens Valuation

Squidoo Lens Valuation What i need is a script for my website, which will calculate how much is squidoo lens worth. Example of what i want can be found here: [login to view URL] I would like to have same thing with some upgrades, it must get details on how much did lens earn in last 6 months and calculate that in lens value. Another thing that needs to be retrived is lens PR (google page rank). Send me PM if you need more info. This needs to work fast and not causing any troubles on server where site is hosted. Please bid only if you are sure you can make this!!! I will not make any payments until I see script demo in action.
