I am sure Jamie will answer when he gets time, but I will offer my help as he just told me on the phone its ok to do so.
Set up fee. (or part of if you are grouping)
£6 per piece.
If you want the change of finish then its an extra £1 per part.
Meaning if you have a gloss piece you want annoed in dust finish, that will be £7.
Or the other way around.
Cant give you a definate price as you may want change of finish on some bits
Dont forget the rammer housing and frame tag in your bits list
Hope that helps
