First off, Hello everyone. I'm new here (on the forum, not to the business). I'm looking for suggestions for the best and cost effective substrate for 24"x 24" hole markers and yardage signs. My client is looking for something that is double sided, durable, and (surprise, surprise) low cost. My only suggestion for it is crezon, ( will still dent when hit with an errant ball, but not as bad as aluminum composite ) but he doesn't really want to pay that much. Any suggestions would be a great help.
