Communication between Bluetooth 4 and Mac

I need an expert in bluetooth 4 protocol that will write a mac application capable of gathering data from a bluetooth 4 device (accelerometer) and transform those data into a UDP-protocol packet. As you probably know bluetooth 4 is quite different from regular bluetooth devices: I'm looking for someone who knows that protocol. Also I need someone to do this job quickly, I would accept only people who will be able to do this work in three days, otherwise it will not be necessary. Thanks
