In order to give you some idea you could check out the decree in AD 177 by Marcus Aurelius where he classifies the munera from being low key to very posh. (CIL II, 6278, l. 29-35) I was quickly browsing my broad library of literature on gladiators but could not find any English book which explains this in detail, only the French "La Mort en Face" by Eric Teyssier on page 418.
Costs for animal shows are stated in the Magerius Mosaic which is today to be found at the Museum of Sousse, Tunisia. A good article on this is by David Bomgardner "The Magerius Mosaic Revisited" in Roman Amphitheatres and Spectacula: a 21st Century Perspective, pp. 165-177.
