Well, do you want the easy way out or do you want the more technical route?
I used to do cartography for a map company years ago. Things have changed a bit I’m sure. But if I was doing it I’d start with your county GIS site, zoom into the area you’re wanting. Save that file as a vector format (editable format, not jpeg, png, etc.) something like a Vector PDF, dxf, or ai format and take that to a large format printer to have scaled and reproduced. But there are many styles and looks of maps and it depends on what you are after.
Let me know, I might can point you in the right direction.
