Startup Idea : App How To

Excuse me for the wrong English. I am Brazilian and I do not speak fluent English, so I used the translator.My idea is to develop an App or collaborative website. the name HOW. Many people people search on Google something like that starts how to ..., how to microwave food, how to make the bed. How to get a job.These are just a few examples. I want to further develop the idea.This would help people seeking solutions to this phrase, because they want a solution to that problem.And in the search results, you will see the best results with reviews of those who have used this solution to your problem and can help others by qualifying for the aid.As I said, I'm still developing the idea. This description is just a preview.I need people to desenvovler developer and business.Remember that ideas that involve person to person relationship, are very well regarded, like Google and Facebook itself.Someone in order to embark on this idea with me?How can we begin? =)
