am not sure if i can request here a custome item but if i can i will try for rct3 you see am making a zoo and i would love the san diego zoo sign  could somebody that knows how to make custome items  for rct3 please make one  please

 

I don't think there's any CS creators on the site anymore. I'd check both the downloads on ShyGuy's World and their forums.

What he said ^^^

I'd suggest a standard billboard,.maybe spruced up with a little CS. Cafeen's letters might also help.

It won't help with the sign, but if you're building a zoo I'd recommend StationJimJrs Zoo Things and Jdrowlands invisible animal fence.
