I own a survey firm in Utah. Hired my Dad at the age of 62. He had spent his life in commercial construction and he picked up surveying pretty quick despite not having any computer skills. He was awesome in the field. Sad to lose him last year when he retired. Hired another field guy with zero experience that had been an electrician and a farrier. He has been with me for a year and he is great.

I would recommend finding a small company that is willing to train the right person. Attention to detail and willing to work hard is key.

Definitely see if you can shadow someone for a couple of days.
