maybe throw up a rough price for general service (oil/filter/plugs), then maybe a diff oil/trans oil change, to things like links/bushes/suspension just to give people an idea. Seems like timing belts are your thing , rough price to get one changed? maybe even turbo swaps/manifold swaps, not everyone needs work right now, but if something where to come up then its always a good reference.
will keep you in mind, if im unable to do it myself
