It's going to be tough for you. There are people who have made movies on a budget less than what you're going to spend on film school.
It can depend on how intuitive you are. Me personally, I'm a learned kind of guy. I rarely figure out how to do something unless I'm looking for that solution or have been taught/read about it. Therefore I read a lot and watch a lot of tutorials.
Would I give up my film school experience in exchange for real world experience. That's a tough one. I'd say no, but back when I did film school, it was a lot cheaper. It was before all the hooha fanfare was out there about film schools and only cost me about $2k a year... Which come to think of it, in today dollars probably comes out to move than $11k.
Some people best learn by doing, others best learn in a learning environment. Which are you?
