Search Engine Marketing Management

Suggestions Search Advertising for a web page golf league?
I am looking for suggestions for marketing to attract customers to my website management of the golf league (I will not mention the place so I'm not accused of spamming). I have an AdWords account, I have gotten great ratings with words keywords such as "Management of the League of Golf" (usually 1 or # 2) on Yahoo and Live.com, and within the top 10 in Google. I have also posted on blogs golf and directories. Golf leagues are seasonal so you basically have a window of 2-3 months each year for new customers. They trickle in to find through other search, but obviously I would like to exploit this as much as possible. I've been considering leaving for some golf and trying to step unsolicited quick to who is behind the counter of the professional golf shop, but I'm not sure how it will happen. Any other suggestions out there? I received a great response of the leagues that are using it, but how to convince others that offer much more than what you can do with a single software program?
I like to see the words ad account. are using conversion tracking, content match? Does it cost per lead and / or sale? But it seems that you need more keywords or a keyword strategy.
