Most of my neon signs were bought from a guy called “Hong Kong Gu”

They were a little bit on the flimsy side and I did have some failures but he was always very prompt at giving me a free replacement when something went wrong. He would also make custom signs for me.

He started an online store which no longer advertises the licensed neon, logos, etc. however I suspect he would make them if requested. https://www.aoos.com/custom-neon-signs.html?gclid=EAIaIQobChMIo6CXpb-p6QIV9uzjBx1OUwQyEAAYASAAEgJ3sPD_BwE

Here is a page with some examples of his offerings previously:
