Simple enough question :~} It depends on how you want to proceed. You can either find a partner and start working toward competing in amateur competitions or you can find a competent pro and do pro am.

Actually either way the most important thing is to find a competent instructor because you'll need one to improve your skills. To find one you like go to a couple of comps and watch the pros until you find one who looks like a good fit. Then go sit in and listen into one or two of his/her lessons to see if they teach in a way that is compatible with how you learn. If you can find a partner it's great but it isn't mandatory and some people don't want one at all. It is up to you...follow your bliss.
