I ran into your same problem last year. I never really wrote a handwritten letter to any school. All I did was wrote an email to several coaches that I had interest attending their school explaining where I was from what positions I played my accomplishments as a student and as an athlete and that I hoped to hear from them in the future. That is all you need to start basically. Shortly thereafter the schools that were interested started showing up and calling me. It does sound like writing one of these letters seems overwhelming but it really isn't if you put your mind to it. I was so overwhelmed writing my first one I needed my mom's help writing it.
