ill throw in my two pence worth here
i dont live in aussieland so dont know your laws so will just work from my own experience

can it be done in a built up area........yes of coarse just remember it is a full time job no days off
you dont need to feed three times a day from that age on twice is fine but on its own it WILL be bored and could eat throught a wooden fence i would put a four foot wire around the yard
i started out in a built up area and did fine but i use to go out of twon to some fields to let them run a near by gallop is a must
a walking machine is a waste of time for a pup period
breaking in .... i know it done differnt there but i break in all my own never had a problem time and patience is key
ask ask and ask questions of trainers you know must are very good to give advice
