Jumper packs might work on a car but these buses, your bus needs major power to get it running.
Well, there are certain things that can happen if you have opened emergency exits, roof hatches etc. They have to be all in series before the starter works at all.
You might be able to hear a loud click in the driver's area when the key is put to on. If not, that is the first thing to chase down and find out why.
You may have a rear start panel for that bus also where you can try to start it also.
Buses don't like to sit like yours has, they need to run to keep from developing a myriad of issues from fuel issues, electrical and such.
You can look for a block heater as well which, if plugged in for 2 hours, normally warms things up enough for much easier starts. These are high compression engines and they hold lots of thick oil when cold, adding resistance to the starter mechanism.
I take it that it doesn't get real cold wherever you live but this won't hurt till you can determine battery strength and condition.
Clean all battery terminals up and connections of those to ground and to the starter itself. Very basic stuff.. read lots in here, similar issues have come up a lot.
