I dont really think that you would find an actual price on a site as each job's different so theres probably not a standard rate to go by.

I think Jay posted a price some time ago, not entirely sure if its his price per hour or an average in his experiance.

One thing Ive thiught is rendering, if your a company grab a few old PC's and make up a render farm this then would stop your workstations being used up rendering (dont knowe if thats what your doing) you then could cost rendering as power consumption, equipment wear and tare, etc etc and then cost it based on that, might make it more competative.

I think a small render farm would make its money back in no time, see if you can get a few old Pc from a college or uni, should be dead cheap to get up and going and save your workstations for working on.

(that is of course if youve not got a render farm!!)

P.S Any chance you could chuck some work my way since were in the same area!! J/K!
