Hi Steve,
I have known this company and the Smith family who own and run this business for years, they are a very professional well respected company.
What they don't know about stone isn't worth knowing, I can guatentee you the products they are selling are of the highest quality.
My advice would be to speak with Brian or Hamish at the showroom who are two of the business owners, they will be the best contacts to advise on how and what products to you.
I hope it goes well for you.
