Actually, the whole point of a P2P centralized hub based SaaS gig like OnGosa is to connect the end-user with the provider, increasing revenue for the provider and fast connections for the end-user. The liability issues and all can be worked out, as noted so many such gigs have cropped up, from shopping, groceries, home repair & maintenance, dog-walking, and of course the car services. Capital is necessary to get buy-in, and take-up will be high in some sports versus another initially, but skiing is not immune, instructors are employees but there is so much many can do when sitting idle, and on busy days others can pick up the slack. Of course, it is all about execution, but I see no issues with the idea. If instructors at Vail are starting at $10/hr, right there is an incentive for ski instructors to sign on, in fact, mountains would too if it helped their sales. The proof of concept has of course to be seen, but it's a damn good idea, done right, it's a winner. It could upend the ski industry. Forget just big-name resorts, every small mountain could have free-lancers, guides - possibilities are endless, and lawyers can work our the details and fine-print, but need, yes, there is a need, in skiing, tennis, sailing, surfing, diving, hang-gliding, mountaineering, hiking, mountain-biking, and so much more.
