Wifi 3,000 feet through brick walls

I am a high schooler and live across the street from a high school that i will go to next year. The wifi there has many services i like (like netflix, pandora, etc.) blocked. I was wondering if there was a way to build a wifi extender that will go to 3,000 feet through a few brick walls. I would like to spend as little money as possible. I have an old satellite dish, an old modem/router that only has a DSL input, and a computer i am using as a server. I have a bit i can spend on this, but not much. Is there any way to do this? Thanks in advance!
