I really don't know of any property management companies to recommend, but if I bring this post to the top maybe someone else will see it who does.
To do a lease to purchase/rent to own, you'd need a real estate attorney to draft something up. Rent to own can get sticky because if they fail to pay, you need to go through the eviction process which will be difficult to do from a distance. Rent to owns have a high rate of failure too.
My personal stance is don't rent your home unless you want to be a landlord. It is not easy being a landlord and it is fraught with risk and heartache (I know of what I speak

). It's much better to drop the price of your home to the point where it is 'a deal' for someone and be done with it.
Just my 2 cents
