When I first got this car I didn't even think to check for AC in a car purchased in Florida, but as I left the lot, "oh hey where's the AC?"

Whoops.

Summers are unbearable. There are a lot of horrible things in this world but I reckon anyone can agree getting into an oven after work every day is just down right terrible.
I have no idea where to start. I'm not very great at cars as this is my first one, but luckily it's had lots of issues for me to research and pay for. The prices I was quoted for the AC ranged from around 1300 for a private mechanic, and 2000 from the dealership. They said the evap and lines are already in, it's "dealer prepped."

Is this something I could do on my own? What parts do I need to do it?

My exact car is the 2011 Chevy Aveo Sedan LS, 1.6L Manual transmission.
