Where to find survey record of newly bought barren property

[Ciro Cuellar]

Hi. I just bought a barren piece of land (.75 acres) and am starting to look into septic contractors so once the system is in I can put a mobile home onto it and rent it out. I found a contractor and he says to get started he needs a land survey, I didn't even know what that was and now have seen online anything from me needing to hire a $500 surveyor or that I can get a copy of my lands survey record at a county office (my property is within an already built urban neighborhood). Any ideas where I can check to see if there is a survey record of my property or the best steps to find a cost effective surveyor? Thanks!
