I saw on the other post that you were listening in about the Hartt School of Music for ceremony musicians. I contacted them and they got back to me today about the pricing. It is not that much cheaper than some other companies I have contacted. If you want to PM me your e-mail I can send you the price list. Or you can e-mail them here

The one plus to it I've found is that the other companies charge for an hour or more and I don't really think I'd need that long. The Hartt School has an option for 45 minutes or less which I think would be perfect as long as people don't show up too early.
