PCB Design for power efficient microcontroller + bluetooth

I need a PCB and Embedded Software Designed to work with these two components

MSP430xxx ([login to view URL]) Microcontroller


CC2540 ([login to view URL]) Bluetooth

The hardware must fit on a single PCB not to large and must run in 'sleep' mode - it will be run of a battery that needs to last 3 years. The purpose of the device is to count a button click- that is all so it wakes on external click only or when bluetooth gets turned on to transfer data(number of clicks) The bluetooth needs to run in power save mode with only uart serial and no other modules in short range communications.

Software embedded needs to hanlde a bluetooth device(eg computer,phone) to connect via PIN and issue simple serial commands (2 or 3) and download number of clicks.


- any parts i can buy for you at local depot,ebay,auction, digiekey, etc. and post it to you.

Some example,blog of your past work is needed. Do not apply if you have example you can prove.

I am not really looking for cheapest but somebody who looks reliable.

Skills: AutoCAD, Electrical Engineering, Manufacturing, Microcontroller, PCB Layout
