Not sure where you call home but move to Nashville at once! I lived there for 10 years and while the music business is as tough or tougher there than anywhere else it is also one of the most friendliest places I have ever lived and worked.
Without being pushy or a pain in the bottom you can get to know who's who in the industry in a very short time. I must confess it was shorter for me because I had free whiskey and wine as I worked for a major spirits producer.
After you are there go to open mic nights and play your music to anyone who will listen to it. I know from experience that many big time acts and producers not only attend these venues but even try out new material of their own.
You will find many people who have contacts and being the friendly town it is it won't be long before you meet some pretty influential people. Now I repeat do not be pushy and try to overpower your contacts as you will be seen as someone only looking out for yourself and you will be dropped like a hot horseshoe!
I guess the real question can only be answered by you (or anyone else with the same dream) and that is . . . how much are you willing to sacrifice to gain the stardom you seek? If the answer contains one "but or maybe" the only other way is to get "real" lucky.
Just my 2 cents, still wishing you the best.
