Otherwise I'd buy a used motor from a heavy equipment salvage yard, something in the 6" to 8" range and either buy an Alltrax 7245 controller, a used speed controller or build an Open Revolt speed controller.
To get 75mph I suspect you are going to have to go with a 72v battery pack, but if you shop around I think you could build the whole thing for less then $2,000.

i think shopping around is my problem. As big as vegas is I cant seem to find a scrap yard with motors I need. And online I cant seem to find the right prices. Are there any online places you'd recommend?
