A native white pine which I like and grow is Southwestern White Pine, Pinus stobiformis. Tree is very hardy but has longer needles which would be suited to a larger size bonsai.
I see you are in zone 5 but you need to include your city, town or general location in your state. I live in a humid area in central MD zone 7a and have to treat the referenced pine with fungicide every month. It should be fine temperature wise in zone 5.
I got mine from evergreengardenworks. Inexpensive and it will put you "in the game" with a white pine.
