Have you considered Stonefire Grill? We use them for parties all the time. Yummy ribs, chiken, tri-tip, salads, & sides. I recently attended a wedding where the budget savvy bride used them for a buffet at less than $10 a plate...set-up, serving & clean-up! Check them out www.stonefiregrill.com Good luck!
