Mowing/Trimming - Large yard/garden

I have about half an acre area that's overgrown. There's existing landscaping along the street, and behind that there's a fairly extensive garden/food forest with fruit trees and paths that are full of weeds. I'll show you exactly where to mow/trim, and where to leave the area alone (there's a map!). I need someone with their own equipment to knock down the high weeds once, then maintain the area every 2-3 weeks moving forward (or as needed). We'll discuss a price for the first job, then maintenance thereafter will be $20/hour.
