Hole in the market? What hole?
Besides, this is a discussion in theory. There isn't any market research presented on this thread. I get a chuckle when I see young entrpeneurs identify "market research" as browsing the web for a few statistics here and there... mostly from unproven sources.
It takes a lot of work to establish a business, and the folks that start out will usually make less than minimum wage when compared to the enormous effort required to get something off the ground (pun intended). Successful business owners are the ones that get to do something they really love, or build on an idea that is simple and reproducable. I'd rather go with the "something you love" concept.
It will be interesting and fun to see these dreams and thought put into action.
