Add Bluetooth to pre-existing chipset.

I have an idea that requires bluetooth technology be added to a pre-existing PCB, the small control unit serves to add a selective feature to a device that normally had no other ability other than on/off, now the device can cycle its electric motor a specific number of times based on a selector switch. I would like to add Bluetooth to this circuit in order to have the device sync up with a cell phone app, it would allow the device to have even more custom features. The current control unit is open source so adding features is supposed to be possible. Please let me know if this is something you would like to work on with me, there is an opportunity for sharing in the wealth if this idea takes off! The industry I'm attempting to influence is a multi-billion dollar activity that grows yearly and is very accepting to new and exciting advancements, I believe I have one. A non disclosure agreement is expected. Thank you for considering this project, the cost/rate etc is negotiable of course, we can discuss that, along with milestones, once the project is accepted.
