No rock stars required to develop this system, but you'll need a crack-sales-team.
This sort of thing may still feel like rocket science to many of your pro-shop guys taking tee times over the phone - and they are probably the gate keepers when it comes to sales and implementation.
There are certainly some serious apprehensions I have about the business. It worries me that there is no one out there searching for this and that it would boil down to a 100% cold-calling sales gig. Also, most, if not all, of these golf courses have the worst looking websites, which leads me to believe that there is no one looking after any web presence or anything web-related.
This actually touches on a bigger issue which I'd love to discuss. What you have here is a very profitable niche, one in which a few early 90s web companies took over, gobbled up all the market share, and then stopped innovating. I see this in a lot of ignored niches.
I second the golf course idea -- sounds like a good opportunity.
