Great idea I could help you launch the app and make it succeed in the market, There are many similar projects in my country but very fast cloase or fail , not so popular maybe I could give you a couple of good suggestions for work because I have experience how they should not work.
I would love to talk to you, My suggestion would be 15 minutes

Sounds like a very nice idea.
Don't forget to validate it before you spend too much time/money on it.
Good luck!

Creating a professional networking app is a good idea, but do not know yet how it will likely be and when it will succeed. Because even in case you build the right product, if the timing is not right, it'll be a failure. Instead of creating an app, there are many platforms where you can create a professional network group for youths which is an easy way for youths to connect and take knowledge there. A few ways to create a professional network for youths are:

Create a Facebook Group
Create a LinkedIn Group
Create a Google+ Community

Invite youths to join these groups, then treat the youths as your audience. Create content that gives them professional guidance and they can use to help themselves. Encourage engagement and sharing. Post new job opportunities there. Publicly (in the private group) acknowledge youths in conversations.
