Posting for a friend.
He is an ex fabricator installer from Kima Glass for 8 years already.
He decided to go freelance because obviously he will earn bigger.
Materials will be listed for you and you can go with him to the supplier to purchase them.
He will then charge for the labor only at a very affordable price and believe me he does his work with great craftsmanship and quality.
I ended up saving 8k to 10k for a job involving 4 sliding glass windows (comparison is based from quotation from other shops/fabricators).
