You're in the heart of the midwest... In my opinion, most of the best teachers are within 6 hours from you!
In no particular order:
Floyd Cooley - DePaul University
Rex Martin - Northwestern
Fritz Kaenzig - University of Michigan
Phil Sinder - Michigan State University
John Stevens - University of Wisconsion Madison
Andy Rummel - Illinois State University
Mark Moore - University of Illinois Urbana-Champaign
Matt Lyon - Ball State
Dan Perantoni - Indiana University
Mark Cox - Central Michigan University
Tim Northcut - Cincinnati Conservatory of Music
Ron Bishop - Oberlin and Cleveland Institute of Music
Thats a great big list of great schools with incredible teachers and ensemble opportunities. You live within very reasonable driving distance of all of them. I recommend you seriously consider some of these schools. I am just finishing my senior year and went through the whole process you're embarking on. What you need to start doing very soon is writing your college essays. Don't wait until the last minute, because they'll suck if you do. Also, start your apps SOON. Or else you'll be spending your Thanksgiving and Christmas breaks doing them (depending on due dates). When you feel like you've gotten a good start on those things, pick your rep. Most of those schools ore going to have very similar audition requirements, so find out soon so you can plan.
The sooner you start working on things, the sooner you'll be done so you can practice and get into whatever school you want. I don't know what instrument/s you're playing on, but take a look at both the Vaughan Williams and Hindemith. If you only play CC or BBb, DO NOT immediately write the Vaughan Williams off. Pokorny just played it with CSO on his york, so why can't you? Anyways, those two solos are staple items for some of the schools on the list I gave you. You said you have worked on excerpts and etudes before. Most schools will ask for one melodic and one technical etude. Pick a Bordogni out that really shows off what you can do well. Find a Kopprasch book, and start working on a number that compliments your technique. I also recommend that you start working on the opening and soli section of Die Meistersinger, the B major section of The Ride, reh. 3 to 6 of Prokofiev 5, the Mahler 1 'solo' from the 3rd mvt, and Petrushka Peasant and Bear solo.
Make connections with teachers. Use your senior year to do some networking and get lessons with teachers on that list, or anyone for that matter! I recommend applying to 4-6 schools that have a good balance of teacher, ensembles, and atmosphere. Sometimes it isn't always best to go to the school with the "A+ studio" and an awesome teacher but has no depth in the ensembles. Pick schools that have: great teachers that you get along with, fascinating ensembles, and a thriving arts community. And getting lessons with teachers in the fall will give you a leg up on the competition in the spring. There is nothing better than walking into an audition and a teacher saying "Hey [insert name]! It's good to see you again. What are you going to play for me today?"
FINALLY. If you are very serious about going directly into performance for your undergraduate, the best piece of advice that I can offer to you is to look into attending Interlochen Arts Academy for your senior year. It is hands down THE best place for a high school student to learn the trade of music. The ensembles are that of a great college music program, and the teachers are world class musicians. Studying at Interlochen will give you a world of knowledge and put you far and above many musicians in struggling public school band programs. Two tubists are graduating this year, and there are 1-2 openings with wonderful scholarship opportunities. The teacher, Tom Riccobono, produces some of the most successful young low brass players out there. Just ask Matt Lyon at Ball State, Nicole Abissi of the Alabama Symphony, Nick Shwartz of the New York Ballet, Carol Jantsch in Philly, Kevin Sanders at University of Memphis, Ben Green with the Zurich Opera John Whitener of the Scottish National Symphony (the list goes on), or any one of his students who went on to Juilliard, NEC, Curtis and many other fine fine institutions. In the fall, I'll be attending DePaul University with Floyd Cooley and the other graduating tubist is going to Oberlin to study with Ron Bishop. Please just give Interlochen a quick look and email me (

Best of luck to you. I really hoppe this information helps. It's coming from someone who was in your exact same position one year ago.
