Attached is a version of what has been posted. It is generic because lacking motor data (exact motor data) it is difficult. RY1 is a standard automotive relay, RY2 would be slaved to RY1 and that is a high current relay (contactor) capable of the max current of both motors.

Oh I didn't know that was the type of schematic you were going to do. I aced doing ladder diagrams in my PLC class, the thing is, we never went over actually "where you buy the relays/contacts and how to hook them up together", so making the ladder diagram I can do in my sleep, but actually buying the right parts is where I struggle.
From the looks of your ladder diagram, you have S2 as the start button, however, RY1 and RY2 will already be energized because S1 is a normal closed button, and S2 is in parallel with RY1.
Wouldn't S2 need to be in series with RY1 if you wanted to use S2 as a "start button" for this circuit? Because right now, RY1 doesn't even care about what S2 does since it's in parallel with it. So the only thing I would be able to do with this current circuit is disconnect power by pressing S1, and if I want to enable power, I would simply let go of S1 depending on what type of switch it is. S2 isn't necessary is it?
