Where to study music?

[mark s]

I am a Senior at the University of Wyoming. I am a psychology major here. I have recently made the decision to transfer out of Wyoming after this spring semester and do a double major of both psychology and music- performance (voice). Now here are the kind of things I'm looking for in a school.

Preferred warmer climate
Voice program- not too selective, I'm still early in my voice studies.
Reasonable annual tuition (maybe 25k a year max, I have residency in colorado)
Medium sized school (between 7-15k students)
Music program- rigorous, challenging

That probably seemed like a contradiction so I'll explain. I want to get into a music program that is challenging and that will push me to limits unimaginable. I am willing to put in hours upon hours of work and time into my vocal studies. But I need a school that isn't too selective at initial audition. I'm not the most talented vocalist out there, I just need to get my foot in the door, and then I know I will work hard to become a more talented vocalist. So I'm looking for a challenging music program that accepts a large amount of people.

Thanks for your help!
