USA Bus Lines

I need help finding cheap transportation from NJ to PA? I'll be flying into the Newark New Jersey Airport at 7:38pm with my two younger siblings (14 and 12). The transportation (Trans-Bridge Lines from the Airport) that we were counting on sends out a bus at 7:30...we miss it...and the next one is at 9:45. We need to take the bus to Bethlehem, Pennsylvania where we'll be picked up. Is there a quicker way to get from Newark to Bethlehem or even Allentown would be better? I really don't want to ask anyone to drive. My brother who would pick us up will be working the night shift so..that's not an option any more. Any cheap suggestions?
