Well, I'll answer my questions. 
I don't have problems with PC's hiring themselves out because they're making better pay going into dungeons themselves than getting paid a flat rate to risk their lives to do it. Going by the recommendations in the DMG, a party of about 6th level is going to have quite a bit more than 6,000 gp...it's a drop in the bucket.
Plus, there's story considerations. The PC's have better things to do than hire themselves out....save/condemn the world, run from local law enforcement, etc. KFQ is what adventurers do on their off days.
Plus, coming up with a quest isn't a real problem for me. I've got a host of little "Minor Excuses To Dungeon Crawl" laying around. If they do hire themselves out, I send 'em on the quest, and bring 'em back, rope 'em back into the story, no probs.
