It's entirely possible to set up tricks right in front of a spectator. Someone just posted a video of David Blaine doing just that. It's called routining and knowing your skills.
Anyway, the suggestions you've been given should give you plenty of material to work with.
Dont get me wrong, you are right for that and i definetly do tricks, what reguires set up, what i can do in front of a spectator. But what i really mean that, i dont like tricks, where you have to use gimmicks like double facers, duplicates etc. or you have to set up whole deck.
