Itsinteraction

I have a idea to built an application that allows one to detect people around you to interact with u ( Face to face, call, video call , chat) . The sole purpose is that sometimes we suddenly like someone in a subway, or Street, or market but we fear to interact or start a conversation. But this application will allow other users near you to see if u r intrested to interact with them . And can successfully reduce the effort and time for both. The user can set range to which it should allow( eg 10 meter, 50 meter, 100 meter etc.) It can be used mainly if someone is travelling alone in bus and needs accompany or in a train. Or waiting for something in a cafe. So i need a coder who can code this application for me... I won't be able to provide money now but I can provide him shares of this application as a mode of payment. I know this idea will grow unicorn one day. So if anyone is interested can come over to it with me. By the way I am 18 years old.
