what assets do these 2 have? do they have commercial licenses for maya? do they use nuke or after effects and have licenses for those? ...prehaps photoshop and zbrush too? are they rendering in mental ray or vray or renderman or something else? they need licenses for those. How many machines do they have? I would work out how much that is going to cost and factor that into the price for their first couple of jobs.
you could go down the open source route. Might make a more interesting project.
