I worked for a survey firm out of Jefferson for about 10 years and did this all the time. If you're going for a complete survey then that involves a little courthouse time (unless you find the firm that actually pinned the subdivision), the actual survey and a plat of your lot which usually is recorded at the courthouse which would be suggested if you're intending to do any type of improvements (fence, hedges)). Do NOT do any improvements without knowing exactly where your pins are located as I've seen countless neighbor disputes which lead to a fence being moved. You'll know a pin when you see it as they're almost always rerod, usually with some kind of cap with the surveyor's number stamped on it. You can do like I did in Bella Vista and rent a metal detector (ok, I didn't rent it, I borrowed one from the firm I worked for) and find them yourself but it's almost always best to have the survey documented, not necessary but definitely suggested.
