If you're starting with flat plate, I would recommend getting it laser cut. It will be a precise and tidy job and every one will be the exact same. You can also fillet any corners you want while you're at it and have all manner of decorative curves and shapes. It's not terribly expensive and you can even get it done online nowadays. Fractory have quite a nice website that quotes instantly - they won't be the cheapest but if it's a one-off it may be the simplest solution to get a ball park price.
