I think I would enlist the help of a commercial real estate agent who specializes in these types of facilities. You can google daycares in your area and see how many come up in your search. Go visit some commercial daycares in your area and see what their set up is like. I know you must meet certain criteria regarding washroom and kitchen facilities.
This is not an easy business especially commercial wise. You will have to come up with something that will make you stand out from the rest. Good luck. I wish you much success
