Hi, I can do a land survey for you.
I use Leica 3D laser scanner and it's used to produce an accurate and detailed map identifying both the natural and man-made feature within an area.
4 acres could be scanned in less than a day, creating 2D drawings would take less than 1 week.
Survey £600 (including travel)
Plan Drawings £500
I look forward to hearing from you.
Regards
Michael
