Limos / shuttles?

Ok, I'm trying to get most of my planning done before September. Venue, photos, flowers, DJ, hotel, all checked! Now for transportation!

Does anyone have any price quotes for limo companies? We'll need 2 limos the day of and are really interested in getting a shuttle at the end of the night to bring guests back to the hotel. If it matters, we're right on the border b/w Nassau and Suffolk.

Thanks in advance!
