Circuit Board Design

I am building a custom fpv racing quadcopter and need to make a power distribution board, with some built in electronics, like two voltage regulators (BEC) for 12 and 5v, an LC filter for filtering power to the fpv camera, OSD (on screen display), OpenLog data logger, and buzzer. Input voltage is between about 10v and 24v (need a little overhead too). Traces for speed controllers (4x V and G, full source voltage, as well as signal and ground from the speed controllers to the flight controller)... also from the voltage regulators to the camera (solder pads) through the LC filter and OSD to the video transmitter (solder pads). There should be a microJST plug to connect the data logger to the flight controller via cable. There will be solder pads for the buzzer. Should be using SMD components wherever possible. I can provide some schematics of each piece (might only have gerber files for some), so mostly just need you to try and fit it all into the shape and size I need. I've attached some images of a couple different PDBs that are for a different frame. Same stuff, different layout.
