It's pretty simple.
1) I give you a bunch of Bitcoin addresses (some of them have A LOT of transactions)
2) You need to generate a text file for each address that contains several columns with the following layout:
[time/date] [transaction amount] [balance] [mt.gox USD/BTC price at time of transaction]
[time/date] [transaction amount] [balance] [mt.gox USD/BTC price at time of transaction]
[time/date] [transaction amount] [balance] [mt.gox USD/BTC price at time of transaction]
...
Basically, I want to plot my net worth over the past year or so. I can do the plotting myself, but getting the data is proving tedious. As I said there are a lot of transactions (thousands) and blockchain and other websites won't display the full history. You have to dig it up and it has to include every single transaction.
Name your price!
