maybe send one stating you will be starting lawn care if you dont get a call from them you will be starting there lawn.
I don't know if that's legal with a service especially when contracts are involved.
You can say if they don't send the contract back then there will be no service.

It is definatetly not legal involving mail order sales.
What you are proposing is the equivilent of this....
You buy a set of blades from a company on the Internet one time. Then the company decides after 6 months that you must need another set. They send them to you and charge your credit card without getting approval from you first.
You take them to court.
They claim that they sent you an email saying that they were sending you a set of blades and would charge you for them unless you called and cancelled them.
Now here's the good part
You claim that you never got the email and therefore don't owe them a dime.
In the past the courts have ruled that you cannot send (or sell) someone something without their prior approval. If you do then that person is not obligated to pay for whatever they got.
I have in the past included a clause making the contract open ended. I still always contact the customer though.
