What are my chances for getting into either IU or Purdue?

I really want to get into either IU or Purdue University. I am unsure of my chances for gaining acceptance. What are my chances if:

I have a 3.17 GPA Senior Male 18
26 ACT
I am at a college prep private school that IU and Purdue Recruit heavily from (Heritage Christian School)
I live in Indiana
I am graduating with the Honors diploma
I have played on the high school basketball, lacrosse, and tennis team
I have hundreds of hours each year of volunteer work
Currently working 20 hours a week at Crew Carwash
Involved with mentoring a elementary student for a year

Also what could I do in order to make my admission chances greater?
