You'll have to be very lucky to find a local fabricator who will do this.
Most of these firms are SMEs (15+ people firms). They don't have the casual approach to take on odd jobs on the side from people walking in. They will only entertain other businesses on bigger projects.
You might be lucky to find one. But I needed some light fabrication work done and was virtually impossible to find one. Sometimes it's money, mostly it would be time. It takes a long time to make 1 off something, cheaper if they're building 5-6 units of the same and can use the same jigs/setup on all units.
One business quoted me a ridiculous price for it and it would have been cheaper to just buy entry level tools and do it myself.
