Limo/Shuttle Quote Needed

for my April 17th, 2010 wedding

i already have my limo's booked, but i would like to price out a limo/shuttle for my guests staying in a hotel to the reception hall beforehand & back to the hotel afterward

Reception starts at 7:30 so i would like the shuttle to start bringing people around 6:30

Reception ends at 1. So i would like it to run about an hour - hour & a half afterward

Hotel - Four Points Sheraton in Plainview
Reception - North Ritz Club

Quotes pleaseeee

TIA

Hi TIA! How about a 27 passenger Trolley?
