Yeah, but can you give me a ballpark cost?
Sure, see ball park pricing here.
In short ... small simple things are less cost than large complex things:
EG - It's about $0.75 for a 2" x 2" plastic faceplate with no holes or engraving
EG - It's about $5 for a custom 20" x 10" stainless steel faceplate with 15 custom holes and engraved signage.
