Facebook Page / Fix Page and Write 3 Posts Weekly

We are a mobile notary public business. "We" really means "me." Have a Facebook page, but am totally lost. Need someone to fix the FB page, make it look sharp, and draw people in to make appointments. Would like to add the Chatbot feature. We don't sell products, just services. Have two locations. Need to write 3 good posts per week. And anything else you could suggest would be helpful.
