To machine that outta a billet is gonna be ALOTTA work , what sort or programming costs ?
If you not keen on the little tab being welded on, then I'd just cut it flat and bend it up

Biggest problem is most laser cutting places have a minimum order, here is SA it's about £15 but for that you can prolly get 5-10 of them cut, still the cheapest way to do it , IMO ofcourse

Been tig welding on and off for 15 years .... Can get it right sometimes ;-)
