Yes, more home runs means more wire. 1000' sounds reasonable to me for 1500 sq. feet.

Maybe consider using 20amp breakers and running 12 AWG Romex instead of 14. This way you may use less breakers, and a little less wire. Although I would still expect you to need 750 ft for that large of a space.

Romex comes in 250 ft. rolls so buy 3 and if you run out buy another- or buy the 1000 ft. upfront and just return the one if you don't need it.
