I want to be this DJs manager?

Ive humbled for a really long time now what i want to do and what career i want to have in my future life. I have always had this "entrepreneur" will in me.

So, the thing is that i have thought about being someones manager and help the artist to grow, promote him and build up his gig schedule.

I have found one DJ near me, who has a really good start. He is having gigs in the big local clubs regularly. He is also coming out with his first single, and is going to be on itunes and spotify. He has a really high potential for music, and i really believe and like his single.

Ive done many researches about how to get heard, how to get involved with the radio and how to get more fans on Facebook etc. I have contacted this artist and asked him how he is promoting himself, getting to play at the clubs etc and he is doing all by himself.

So, i thought that maybe i should ask him for a coupe of coffee and talk about his future plans, what he want to do and how far he is willing to go with his career? My plan is to tell him that im willing to do as much as possible to make him more famous for free at the beginning (because i want to learn). And that i will have meeting with radio station leaders and talk with them about this DJ and get them to play his songs on the radios. Whatever he thinks is cool! This is really something i burn for. Is this a good start, what do you suggest me to do? Is this a good plan?
