Adding velocity

Ok im 5 ft 10 in and weigh about 155 pounds. Right now my 4 seam fastball sits in the high 70’s to low 80’s. Im a sophomore in high school and i have pitched against some of the top organizations in the area (North Carolina) and dominated. I have great movement on all my pitches and have great location. This summer i plan to play a lot of IMPACT baseball showcase tournaments to get noticed. I also plan on hiring a personal trainer from lifestyle fitness to help me increase my velocity and working with our pitching coach to perfect my technique. I need to know if there is any way i can go to a D1 college for baseball. Ive heard of some people that top out at 86 mph going to the university of north carolina but just please respond if you think that working out and hiring a personal trainer to help get my strength up will help. Thx alot!
