GetAFreelancer.com has a job for you if you need some high-paid work -- write a remote keylogger.

Here are the project requirements:

We need a keylogger that can be installed remotely.

Description:
The main purpose is that the user A can send an email with a program to install (example: a game or a funny program) to the person B. When the person B install the program on his computer, he is installing at the same time an invisible keylogger on his computer. Then the person A is receiving the report by email of every keystrokes that the person B is doing on his computer.

They only want to pay $250 to $750, which seems fair given that the requirements don't include undetectability. For that low a contract price, it seems only fair to give the victim a fighting chance.
