I'm NJ so this doesn't matter to me at all. But looking at charter costs this is going to be expensive. You might better served by booking more than one bus to do local stretches so that the bus starting Raleigh doesn't end up in Indy. Book a bus from Raleigh to Columbus. And an Indy bus from Columbus to Indy. That way you are not paying for a driver to sleep 4 nights in Indy.
The other benefit is you can try to book other buses from other locations to meet up with you.
Also, you might try putting up some people from a few hours away so they can meet you in Raleigh, rather than diverting the bus to them. That way people are paying for the trip from Raleigh as well.
Good Luck. Can't wait to see the on the bus pictures afterwards.
