Matt, both Sobon and Benson books have suggestions on wiring a frame. These can be shown to the electrician. You may find the local electricians have little experience with timbered buildings. Some will make a mountain out of it and some will take it on excitedly. Check around and have them come by and have a look, then select. They will have a tight schedule this time of the year. They may work with you with opinions on what will work and what to avoid, ask if they would work this way with you. Hope it works out. Tim
