There are a few websites that do something similar to what I'm looking for - essentially scanning private keys on ethereum and returning number of transactions that have taken place within the address.

This site is one example: (you need an account to see links)

I'm looking for something standalone though, that I can run off my laptop in the background but haven't found anything available that can do this.

Would anybody be able to put this together? I feel like it should be pretty simple for those who know how to code - that's just not my specialty.

I could offer to pay for something like this for anybody who would be interested in taking a crack at it.
