Very interested in starting to provide sport massage to sports teams in my area. Any recommendations or advices?

What level of teams are you hoping to work with? For high school or college teams, I would advise you to contact the coaches directly with a letter of introduction with an offer for a free 30-minute session with you, to show what you can provide to their teams. For the college teams, I would also strongly advise you to contact the assistant coaches and athletic trainers, as they often are better referrals to you (the head coaches are focused on the "big picture").
For professional teams, you should look up the team's athletic trainer and conditioning coach for introduction letters. They are the ones who will be responsible for an athlete's rehabilitation and performance, and more likely to refer to a massage therapist.

Thanks for the heads-up in getting to do massage for sports teams. I already do massages for long distance bike riders. I was not sure on how to start with sports teams. With your timely and kind advice, I can now move ahead with this in my area.

Thanks, Heather. It can require time and persistence to get your foot in the door. My marketing/networking efforts working with a local running club created my opportunity to become a massage therapist to the Univ. of Michigan track teams.
