Need a creative golf logo for web based company

20underpar.com

I am starting a web-based multi media golf marketing company that helps market golf courses grow there business selling discount membership cards to area golfers. Each paid membership gives the golfer 20% off greens fees for every golf course that participates. My goal is to bring the two together - the E-Harmony of golf! The company name is 20underpar.com. The tagline is 'Tons of courses. 20% off".

I am targeting golfers and golf courses. I am targeting golfers who will golf more than 5 times per year or people that will want to purchase gift memberships to friends or family that like to save money while golfing.

I am targeting golf courses that are looking for a cost effective way to promote their courses.

My company will be edgy and provocative in its marketing approach. We will push the envelop to get attention. We are looking for a logo to do the same.

I like the logo to be on a golf ball with my tagline. I want the logo to be above the tagline with the logo and tagline to consume the same footprint. I want the web address incorporated as the logo so people can easily assimilate the website with the company. The tagline must be easily differentiated and readable.

20UNDERPAR.COM LOGO
Tons of Courses. 20% off.

I like these logos as inspiration:
http://www.tpcmichigan.com/ - simplicity and color sceme

http://www.ashworthgolf.com/ - unique
http://www.naturevalleygolf.com/

I am open to color concepts - I tend to like bolder colors.

I am not too familiar with file formats so please use the most common types.
