If you’re really interested in building a full language and developing languages to their fullest potential in a fantasy setting, I’d recommend picking up Holly Lisle’s Create A Language Clinic. Most of her clinics are actually worth it (although maybe a bit on the steep side for some people), but I’d say that the language one was certainly the most helpful for me personally. They aren’t exceptionally deep, and they do rely on the author to be decent at their craft, and at least decently well read, but they also help to make certain things feel less, artificial. Fully functional languages in a otherworldly setting can, if used sparingly, really help to flesh out the culture of a world.
If you just want quick names http://www.seventhsanctum.com/ probably has something. (I know they have a greek sounding namer). Just be careful to Google anything it spits out of its greek name generator, as it sometimes produces words that are, or close to, real words.
