If one party wants out of a business contract without good reason, what can the other party do?

I'm the president of a cleaning company in Florida . we are an LLC. The owner of a few condo units contracted with me to clean their units as per a schedule which gets emailed back and forth between us I've been working for them for a year. Today I received an email where buy the owner said I would no longer be needed however we have a contract that is automatically renewed at the beginning of May and he had two weeks in April at the end of April to void the renewal but he never elected to do that now he contacts me and wants to cancel at the last minute and I have already have a schedule with employees to be cleaning two of the units next week. I'm not quite sure what to do in this case because I'm new into the world of contract. But I don't want to just get stepped on like this I feel like I must have rights due to the signed contract. We have been fulfilling our end to a T. I've not received any complaints about the cleaning. Any advice appreciated.
