If you got the cash, get your promoter license, have your own training camp with your own trainer/sparring partners and then throw a local event. Make sure you have insurance, budget and approval in your state and province.
This way, you set up the match, control the event and are master of your domain.
This is my path if my net profit grows. I have trainers in boxing,sambo,, Tang Soo Do and Kung Fu. Goal would be to have my own event and keep it small time like fight club. Like in some dingy basement at some 90s/2000s music night event. I would be also headlining because I am awesome!
Also don't overbook fighters, goal is to not make money but get legitimized to be on Sherdog fight finder. Keep it fun, get some sexy ring girls and have it be a jovial fun event.
