I have a phantom 4 rtk and topcon gps base and rover. I mostly do topography work for job sites. I can provide results in state plane coordinates or if you give me a .pdf map and text file of control points I can localize and make the topo in whatever coordinate system the job is in. I have a lot of experience getting authorizations. I also do some progress videos/ pictures of job sites. I own pix4d mapper so I can process my own images into a 2d mosaic and contour lines (.dwg) if the job is in state plane I can make a nice geolocated .kmz I also can do estimating so I can do a takeoff of your job and compare it to my drone data to tell you volume information and cut fill maps etc...
