Australian shepherd or collie?

i'm planning to get a dog and i was thinking maybe i could wake up at 5:30 every morning so that i have an hour to exercise the dog and then give its food then put it to its crate with lots of time ocupying toys and maybe he'll sleep (cus i would be endlessly exercising him for an hour in the morning and he has a full stomach to ease him into sleeping) and then i'll come back at 2:30 and take him out again, exercise him for a long time(either 1-3 hours, which should i do??) and take him back in, give him lessons (to tire him mentely) do my hw, eat dinner (for me), feed my dog its dinner, then go outside for bathroom, then comeback in at around 9-10 pm and let him sleep in my room on a dog bed (not the crate) and start the whole thing over again the next day. i could do this all week long, including saturday and sunday. which dog would be better, since i live in a duplex (half a hous) and have a small woods in my back yard, but no fencing
