That's an excellent idea. That's a real service which could be done on not too much money. It reminds me of "Untours" a company in Europe where travellers can rent a cottage, apartment, or whatever in a city and they will have access to someone who speaks their language and can also recommend restaurants, places to go, routes to take, what to avoid, and so forth. It's like having a tour guide without being on a tour. Yours works the same way.

Don't you guys have co-workers??? What about asking someone out on a date to show you around? If you're somewhat cute and not too scary, they'll probably show you all the fun stuff!
