where can i get college logo branding irons that attach to the grate of a grill?

i first saw this branding iron on "unwrapped", it is not handheld and it attaches to the grate of the grill. you lay the meat on the attachemnt and it brands the meat

I once cut out of stainless steel 3.5 mm thick, names & wired them to the barbeque grills & every steak cook on each grill had a name branded in it from what ever grill it was cook on. They were cut on a steel bladed bandsaw & easy to make & just wired to the grills.
