Startup Idea : Save children from child labor and begging

Here is the problem:I have seen many children which are under 18 years they are roaming on streets and doing work on tea stall small hotels for one time food. Here is the solution: We are going to build an app,that where we go on street or any tea stall ,we have to take a photo of that particular child and upload in our app with place and send it to orphanage and NGO's who taking responsibility of it .
