Parts list for S500 build

I’m new to quad copter but not to aerial imagery for surveying purposeso. I have just ordered the Navio2 FC and now I am having difficulty selecting the rest of my parts. I am going to be using a Go Pro Hero3+ that has a high accuracy lens already installed but I haven’t chosen my gymbal yet. I need help choosing motors, ESC, receiver, not sure what else I need. Any help would be appreciated.
