if I want the fire department to put out a fire, they should be doing it. If theirs stuck in a tree, they do it. what kind of contracts would I need for police? unless I have people violating my property.

depends with who and how you contract.
you'll also need contracts with police and fire brigade, if you want their services

A medic would be under the same such laws
