Josh, where are you based?
Researching the boarding business from books is not going to help you an awful lot. Hands on experience in handling and training dogs is an absolute must.
Even if you do Certificate 3 and 4 in animal husbandry, you are still going to need years of hands on work before you will have enough experience to handle the responsability of running a boarding business. You never stop learning and I have been around dogs for 30 years.
So that you get to see the good and the bad of what can happen to dogs, I would recommend you do work experience and voluntary work at RSPCA and a local vet hospital. After you have done that for at least 12 months, try and get a job at a larger kennel facility.
From a cost point of view, unless your old man is going to bank role you, you are going to need a huge pile of money.
My kennel set up caters for 60 dogs and 40 cats and will cost over $350,000 before I am finished. That does not include the land.
Councils do not like kennels in urban or semi urban areas so you are going to have to have an acreage block far enough out of these areas not to trigger zoning conditions. You will need to allow at least 2 years to get an application through your local council and if somebody objects, that will stretch to 3 years and more.
I applaud your enthuisiasm and hope the above helps you.
