For a Turkish bazar I would pick up some West Wind Gypsies, Artizan and Brigade Games Fezed gentlemen in suits and perhaps, depending of the era, a command pack from BG with WWI Turkish officer. Since you definitely need some kaftans and fezes in the pictures I, for civilians, would probably use indian or arabian miniatures (Eureka, Foundry) but do head swaps for fezed heads. There really should be no or few turbans, just takkes (you know, 'kippas'), fezes and Stetsons, oh, en veiled or scarved women but no bourkhas.
