How long will it take to get into Marine boot camp with a fixed wing aircraft maintenance mos after signing up?

I plan to become a Marine Corps Aviator. I'm 20 right now. I want to go ahead and go into the Marines as enlisted and do fixed wing maintenance for fighter jets. I will be going to college after signing up. I just wanna know how long it will take to get to boot camp after putting my John Han on the contract with that MOS?
