We have simple 20' x 16' concrete patio that I want to resurface. I had planned to do it using my own elbow grease (quarantine project) using self-leveling cement. I still want to do that (i.e., get my hands dirty) but I'd like to hire an experienced pro as a kind of consultant, i.e., set me straight on my assumptions (mostly garnered from DIY articles and YouTube videos on the topic) and to assist on-site if s/he is interested in that.
