Limo/Bus Help!

FH and I have been engaged for almost a year (September) and the planning has gone fairly well (you know how mom's can be ) Well this is the first thing we have had an argument about...Limo's/Bus's. Does anyone have a good reputable company that they are using or know someone who used that will not break our bank. I know I need a few different things but I feel paying $2,000 is ridiculous...am I being cheap??? HELP!!
