I don't do Greek myself, so I can't speak from experience. However, I believe Mary at Moonlight offers Greek at no extra charge. She's not a girl, though; she's in her late forties.
ive noticed a lot of younger sp's in mp's. the ind. women are more in their 30's. id suggest either e.b/t.o or broadways for the younger girls. but if anyone can refer a good ind. girl in their early 20's, help a brother out!
