Wakeboarding is too niche. If your good at wakeboarding, it is easy to get discovered. I'm sure the numbers reflect that in your market research.
I am going to be the downer here and tell you that these sites already exist.. However, as a matter of fact, the majority of recruiting online is done via Facebook and Twitter since the NCAA has very loose regulations on private messaging through social media. NCAA is where the big money will be, and I don't see a solution to a problem here. (I am not aware of Canada's collegiate athletic association at the moment, but I'm sure it is similar to the NCAA)
Good Luck with your business.
