The bending is easy and could easily be done at home by using pre cut width's and clamping the material between 2 blocks of substantial wood then mending by hand and manipulating square/flat using flat block/mallet/ combo.

Not sure how you intend to mount/arrange this but if it's intended to free stand IE: Floor or Cabinet then Personaly as you have it designed then I don't think 200 x 6.75mm Ali is any where near strong enough to hold a TV.? . . . Would think about some gusseting or bracing.!
