Thanks for the suggestions, guys. I really appreciate them. All of the sources you mentioned do beautiful work - I'm particularly pleased to hear that Grimm does commissions, as I've always been extremely impressed by his work, but it's going to be hard trying to figure out how to go with just the same. I haven't seen a website or a recommendation made in this thread yet that hasn't completely impressed me!
The idea would be to get "Club Lao" the Shanghai nightclub, made, as well as at least one other piece, so that they can be used with sets like .45 Adventures. After I figure out what I'm going to need, I'll start making some inquiries.
Thank you again, much appreciated!
