I would expect the Icelandic hand weaver would not have any spare capacity, nor be able to provide the output you envisage.
- it was only as a guide to possible prices you could expect for something remotely similar.

My main concern is still the disparity of the fabrics between kilts and scarves - and also that you want to have bespoke tartans made for you - there is an implied cost for just in the luxury yarn you mention and the setting up of the loom.
