I am a non driver and need a truck for my work, I would like to insure my helper to drive for me any problems? 
It should not be a problem . You will need a commercial auto insurance policy . The rate will be dependent to some extent on the driving record of your helper . If you are a non-driver as the result of prior driving record the rate could also be affected . If you are a non-driver as the result of disability or never having been licensed , there would be no adverse affect on the rate .
