text: You call and ask for a quote. Most of the time you pay per hour and it would depend on teh loation ( in the field or in the studio).  If you need the treatment, direction,vidography and post production you should call C2 produtions ( I do nto have the number sorry) in Houston Texas. You get the best deal if they have packages.  It will also depend on the medium that you are wanting to broadcast, is this television, internet? I hope this gives you a start.
