App Store Scraper Historical Data (Android & Itunes)

We are looking for scraped historical data from mobile application stores (Itunes, Android Market, W7 Marketplace, etc.). While we also want the current (most recent) data, we are especially interested in historical data collected at intervals (monthly) over the history of the marketplace. Effectively, monthly snapshots of the marketplace. The further back (and more complete) the data goes, the more valuable it is.

We would like the following data points scraped and organised in some form of database (.xls file is fine).

Application ID & Name

Developer Name, URL & Email (if possible)

Application Rating & # of Votes

Date of Entry into Marketplace

Date of Exit (if there is some way to measure when the application has ceased to be available)

Version /Update

Price

# of Downloads (if possible). Where this is not available, the category (ex. +250,000) will suffice if accompanied by an algorithm for estimating the number of downloads.

Pay Version (Free, Paid, In-app payments) - May be combined with price variable.

Top 10/20/50/100 ranking. (may be a binary value for that period)

Complexity (size of memory)

We are looking for the most data possible. If you do not have 100% of what we are looking for, feel free to still bid. However, we will award the prize based on who has the most complete data (going the furthest back). Also, if you have data on other app-stores (other than Android, Itunes or W7) feel free to include them in your bid.
