All About Pocket Knives

Several of my Queen and Remington Bullet slipjoint knives have too much side to side blade play. I don't want to risk damaging my knives by trying to tighten the blades myself, so who would you recommend to do this, and what would be an approximate fee per knife? Thanks for any replies.

Dale (Orvet) and Muskratman would be a couple of guys that could do it.
I am sure there are others here that will do the work for a few bucks.
Everyone may be full right now....
