To me, it sounds like an incredibly bad idea. Sure, it will make money eventually, but it will take ages for it to become profitable (profitable when taking time investment into account), in the current market it's fairly risky, and it has virtually no chance of being a runaway success, since it's already been done countless times.

Instead of choosing a business model and an industry simply because you know them, why not search until you find an underdeveloped market, then profit from that?
