SkiPro- learn skills from others nearby you

We are surrounded by so many people, who have specialization in different skills. I intend to build an app through which people can opt to learn or teach a skill. The app requires people to create a profile, set up the skills they want to learn/want to teach. Based on this an algorithm will help them to find the closest person who knows/wants those skills and ready to teach you or learn from you.
