Design me a Product

Hi there, I am looking for a raspberry pi expert that can develop custom image/boot/gui for my realtime image viewer and power management system circuit/code as well. Below are the details: Board: Raspberry Pi 3 Input: Pi noir v2 camera Output device: Raspberry Pi 7" Touch Screen Display with 10 Finger Cap Touch Output image: Realtime image with histogram equalization Power management: LiPo battery with start/shutdown button Sequence: When I push button start/ON, system loading straight to dedicated program (realtime imaging). When i push the button start/ON again for certain period, the system will shutdown.
