I planned on the same thing - here is what I did -
2nd semester of my sophomore year I took a bunch of general classes from my UW school - all online classes. So I was a full-time student still in a 4-year UW school but could do it from where ever I wanted.
My buddy and I took the boat down to Winter Haven, FL - first thing I did was register to vote there and get a drivers liscense (to establish residency). I wanted to transfer down there - so I figured I would do the online classes for 5 months (2nd semester) - spend the summer there, and then only have 1 semester of out-of-state tuition..... which was about what I was paying in-state in Wisconsin.
The semester passed and when I went to meet with an advisor at USF and UCF found out almost nothing was going to transfer smooth. So after a lot of trying to work the advisors to get things to count for credit they basicall said no,
It was stupid things like I had taken "Differential Equations and Linera Algebra" - a 5 credit mix of D.E. and Lin Algebra, but those schools had just 1 or the other, and wouldn't let mine count for either....
After all was said and done, I came back here after 8 months down there and am just finishing my degree here.
Business is a fairly general degree so you should have better luck than me.
+1 for Valencia and or Polk CC to get started - the out of state tuition was cheaper there than my in-state.... and USF has a smaller branch in Lakeland that could be an option.
