I’m wondering about do-it-yourself concrete surfacing / texturing. I had a quote of /sq ft and just about fell off my bar stool (note to file: Don’t go shopping for contractors in the tavern)

I heard of a guy who did his own texturing by wrapping a t-shirt around a paint roller and he ended up with a very sleek slate-like appearance.

This is an exterior sidewalk and driveway.

Any thoughts from the experts?
/ft??? That’s about k for 1200sqft!! The concrete is going to cost me about k. For 8 hours work for two guys, that works out to about 0/hr per man. You guys have GOT to be joking.
