Bill Malone is the best!!! if u don't have his dvd's, get them NOW!!! i use 95% of the tricks, and the ones i don't use, r because they need gimmicks, but i'll get those soon as well. he has so many great card effects u can do:
gemini twins (my favorit)
sam the bellhop (not sure if this would be good for u, coz u want short stuff, but u can change the story to the inviermont u perform in)
and lots of more.
i would also recommend the art of card manipulation. after u do walkaround, or befor u do walkaround, u can get on the stage and do some card manipulation stuff. i got a special deck for it, which is thiner and has 4 indexes, instead of 2 (for fans). the deck drags a lot attantion and u can get the attantion u need in no time.
u probably have all what i said, but i just hope i helped with those few suggestions. if u don't have color changing knives, get them now! their the best for this sort of stuff. u could also get sankey linking rings, and borrow a ring and link it in as well.
those r just a few thoughts, hope they will benefit u.
