Build a EMG sensor to measure left and right fingers movements.

I want to build a system that can measure the movements of fingers based on the EMG signals. Ideally the system should be able to diffrentiate between the fingers and can records movements of multiple fingers simultaneously. If that is not possible than it should be atleast record the signal so that we can do analysis on that afterwards. The price can be negotiable but there will be milestone for every steps that we will discussed later.
If you have read the description till here type SIGNALS before bidding.
