I have a CDL and there's a slight possibility that I could do it since I live in Wisconsin but....
You basically have no plan here.
What kind of bus is it?
Can it even make a drive like this, halfway across the country? If it's some rusty piece of junk that's been sitting in someone's backyard for 10 years, then you couldn't pay me enough money to go near it.
What would you pay to do this? You're being very vague, we need definite answers regarding compensation. " inwhich case your payment would be the free ride lmk" is not exactly reassuring to say the least.
Finally, I have no desire to break the law and I value my license so unless if you have a CDL, you really shouldn't be driving the bus at all. Especially not across state lines as then you're subject to federal laws.
And then there's stuff like temp registration, insurance, tolls, etc.
