It always pays off to search your direct area. Just cruise around an industrial zone near you and make mental notes what kind of companies are situated near you.

I live in a rather small community but there are 3 metal shops doing a variaty of services (I looked them up on the internet). Also a displaybuilder using mostly polycarb and an used carparts dealer within 800m from my home.

A new shop opened up recently claiming to be able to weld anything and it smartly situated itself close to the three metalshops. If I ever decide to go for titanium I'll check in with him lugging a case of beer

And all ik had to do was take my bicycle and make a quick round and take some notes.

Strangly I never had to use/contact any of them finding easier resources online but it never hurts just to know.
