I think it would be great to have another professional kiltmaker on board. Sure it might be competition for the others here, but you might offer us something that no one else does. It sounds like you've thought this through. Perhaps you should make up a batch of the products you are wanting to offer and let some of the members give them a test run. Discuss with them in a private forum the positives and negatives of your products.
Just be realistic in your production output. Keep us informed.
