Tad i myself have only been installing for 9 years now and will in my case disagree with you 100%. I install some of the most elaborate ponds with the top of the line filtration systems ranging from bogs, external, bottom drains or bottom suction grids, settling chambers, etc......now in my case i have worked with some of the top installers in the country and learned more in the past few years than some installers in 30 yrs. Yes i do agree insurance is a def plus. Now with that said i have notice that you have extensive knowledge of the pond industry yourself and would not hesitate to inquire your services....i have watched your post and such on here for a few years now.
