Customer appreciation

When I was in the coast guard if you were the first crew stationed on a brand new boat you were called a plank owner and got benefits for being a plank owner.
     Well I was thinking of how I could show my appreciation to my first group of customers since I launched this company in May.  I was thinking maybe you would get permanent discounts and free services.  Possibly all customers from May till the end of August.  I am looking for ideas.
