Transportation help

I am thinking about getting a shuttle for guests from hotel to RH and also getting a Roles Royce for FH and I.
Does anyone have a ballpark number of how much this may cost?

TIA

We got a coach bus to the reception and a bus and shuttle back to the hotel b/c we had 80 people staying over (including parents/bridal party).

Our coach bus was $1100 and the shuttle one-way was $350.
