Required Android,Electrical Engineering freelancer for Design bluetooth enabled thermometer job

I'm looking for an agency or freelancer to help me design and manufacture a bluetooth enabled thermometer that will communicate with an Android application. I need help primarily on the hardware side, to design and build a prototype that will be used to raise funds in a crowdfunding campaign. This is a project I will manage in my spare time, so keeping costs low and timelines short are a priority.
