Hie,
It won't be a issue, the best could be done in a pdf format, as many things wont change, but furthermore it can also be done in word, but personally that won't be a perfect solution, if you need to edit and create multiple copies with different figures, it can be done best in PDF, but that totally depends upon the format, if you could provide me one of the copies then i could tell you which can be edited and which cannot, as you want the format should stay intact, so just for that i would require a sample copy to check and only upon which i could let you know the best price for the work done.
