I would search the USAT website and try to find a coach in your area and let them evaluate you and they can let you know what you need improvments on and help you achieve those goals.
I would do this! Sit down and list out your goals and from that decide what you need to do to attain them. Once you know where you want to go it will be a little easier to get there. You can always hire a coach, but he will want to know the same thing.
