Can anyone provide a bus for guest transportation for less than $500?

My wedding is on Sunday, November 12, 2006.

I don't know the number of guests I would have, but I am looking for a bus to transport my guests to and from my hotel in Plainview to my reception site in Bayville. Cocktail hour 4:30 - Wedding ends at 10. I am on a budget, and I can only do this if the price is right.

Please only respond if you can do this for less than $500. Not interested in vans due to elderly relatives who cannot get into and out of vans.

Thank you!
