Rick at Shoreline is "old school."
Some would criticise that and say a more "professional" training organisation would be better.
IMHO you can learn more from the "old school" trainers than you ever will from the "professional" at Ardmore or somewhere. It is far easier to retrospectively lift your professional standards, if that is even required, to meet todays PC bulls**t world, than it is to learn the skills required to stay alive in the first place from a career instructor.
I say that as advice specifically for somebody contemplating the ag/utility sector. It might be different for a career in the IFR/corporate type of role.
