Help with sunless lawn

I just bought a house a few months ago and want to essentially start over with my backyard. It gets little-to-no sunlight so I’m thinking I’m gonna have to do fescue.. there looks to be weeds and what looks like several types of grass growing splotchy but overall pretty much just dirt. What is the quickest and most economical way to get this back yard looking good?

NOTE: I’m located in North Georgia
