Why, exactly, do you want to dedicate your life to something that pays nothing and offers no real job opportunities? I would strongly consider doing something that has better prospects and just organizing your life to do a ton of BJJ on the side. Have you ever trained like a pro for even a month, as in 2x a day 6x a week plus conditioning on the side (not to mention teaching kids and privates to try and scrape by and make ends meet while living in a tiny apartment in the ghetto you share with three other would be pros)? Not to mention you're a blue belt which means you've probably done this for what, a year or two? The honeymoon's not even over yet. Unless you're a poor kid from the favelas or your family is so rich that you can just do whatever the hell you want BJJ doesn't make a lot of sense as a career. Plus, even what little rewards there are are pretty much contingent on winning a world title which very few do. It would just be sad if you woke up and realized that you were 30 and all you had was really good BJJ, no way to start or support a family or prospects for any career other than teaching at a gym.
All that said, if I was young and wanted to be a pro I'd probably save as much money as I could and then move to Sao Paulo and train at Cicero Costa's. Brazil is much cheaper and your money will go further, and that gym is solely dedicated to competition and you can literally train as much as you can physically handle. If I was staying in the US I'd go to Atos HQ and train with Galvao, since you would also have an in with the Mendes bros. That's a very strong team with almost all their talent concentrated in a relatively small area in SoCal. Of course, it will cost a lot more to live and train there. It's not like you're going to get to do all this for free.
Again, this is a terrible idea that has very little hope of creating a good life for you, but whatever. If you're young enough you could always do it for a few years and when you get tired of being beat up and poor you can still go to school or learn a trade. And if you don't get tired of it, well, I guess it was the right choice at least in terms of enjoying life. Though I'd probably at least go to community college on the side for business so that if you do start a school you at least have some idea how to market and run it (which school owners spend far more time on than teaching for the most part).
