The Kodak Master 8x10 is a good metal field camera that you can get for usually around $1000 or less. They are all used, so you will need to do some shopping. A good portrait lens is really any focal length from 300mm to 420mm, as long as it covers film. I have used both a Ries tripod and a large medium Bogen tripod with a sturdy head. A metal field camera is going to be slightly heavy, so a sturdy tripod is a must, not a lightweight one.
