Oil painting

I am in need of an artist to create a large oil painting for me. The painting will be larger than 24x36 inches and I already have a specific idea in mind. I require assistance in finding a suitable canvas to use. The artist should have experience in oil painting as I am looking for exceptional work. Experience with large pieces is preferred. If you accept this project, I will need to see samples of your past work before work commences. Thank you.
