Need Help with Terminology & Source
Am bidding a job that will have among other things 5 - 6 concrete trapeziums (truncated pyramid) with lettering on them. The trapeziums will be 16.5" square at the top, 22" square at the bottom & 21" high.
I would sub this part of the job out hopefully to someone that is within 50 - 60 miles of me. They could do a better, quicker job of it than me.
Who would do this professionally & what would they be called? Cold caster? Mold maker?
Any suggestions of someone who could do it? Really appreciate your help.
