obviously, you must be a time traveller, wanting to use modern technology to move ancient paper/papyrus scrolls instead of using email like we do in 2014.
You do not specify weight, but please make sure your master/King/royal writer refrain from using heavy wooden or solid gold rollers, or this project may not fly, and you can loose your head for disappointing your ancient masters.
It can certainly be done, provided the weight of the cocuments is not too great. let us know what kind of weight you want to move, and we might be better able to recommend a particular copter.
The question of whether to buy something built or build something is a matter of balancing money with time. Anyone could figure out how to build one eventually, and could expect it to cost them less if they did it well. However, it might take longer than you want, so buying something already built is likely a good option for you on a timed project.
