Startup Idea : uber.com idea for mom cooking

I was reading uber.com story recently; basically it turns everyone into a taxi driver. I was thinking of this uber.com idea, the core elements are: (a) a guy with a skill of driving and a car, (b)customer who needs this skill, (c) aggregate all of ‘a’ and ‘b’ in one platform. As you are the entrepreneur in mind, a great idea can use in the similar but different market. Then, I was thinking of a mom cooking for your dinner model. Here is the idea. Problem: You all agree that for busy career women, it’s really hard to prepare dinner after work. There are problems and entrepreneurs are aiming to solve. Solution: There are already many mom who are preparing for their kids dinner. Why not just cook additional more for the customer? a. For people who are already preparing for their home dinner. In other word, anyone who can cook, they can come to this MomCook.com (example). The site will show case the nicely photo of the dishes each chef served (like airbnb.com). b. Career women can just go to the web, order prefer dinner cooking. Pick up the dinner of the chief’s home in the evening, and enjoy a home cooking meal.
