How to ensure tenant does not hold over after lease expiration?

I'd like to make sure tenants get out when the lease is up and I want them to know I mean business, how to I do this? I was pretty flexible when they moved in (ie they told me one date but moved in later, thus, paid less for first 'month'). I do not wish to deal with their nonsense at move out so I'd like to give them two options: Out by 16th of the month or 1st of the month. I know I have to give them 90 days notice but I do not wish to budge if they need extra X amount of days.

1. Do they need to agree to lease termination by signing something or can I just mail the letter without signatures and keep a copy of it?

2. Can I stipulate in the lease termination document that I will be charging $150 per day if they don't move out by the chosen date?
