Welcome to the site, by the way!
Lurking or simply just reading old threads on builds, powerplants, you name it, are invaluable in learning from others on what works and what might work with hefty amounts of $$ thrown at it.
Making the best for you decision on just the right bus the first time, is good for morale throughout the build out process. You really don't want to spend $3,000+ on a bus with underlying rust issues or mechanical issues only to find out remedial works will bankrupt you before you even get to converting it to your liking.
Good luck on your research and ultimate decision on getting into the hobby.
