I'm sorry for sounding harsh, but this seems like a classic case of a feature instead of a startup. Based on the way you describe it, this is an enhancement that Yelp could add. Sure, it will be harder for them to do so than for a nimble startup focusing solely on this feature, but Yelp has an huge, huge advantage: they already have their network. For you, building out a product with this feature is just the very beginning. At that point, you'll have to face your biggest obstacle: attracting a critical mass of users. As a potential investor, I would be far more interested in hearing how you plan to accomplish this.
