If you can make a decent drawing of what you need (it doesn't have to be 
a draughtsmanlike job, as long as the form and measurements are clearly 
shown), I bet you can find someone in your radio club, or a personal 
friend, or someone on a list you frequent to make it for a nominal cost 
(you would probably need to pay for the raw material, although I don't 
charge for anything that comes out of my scrap pile and this is true of 
many other home shop machinists).  HSMs are behind every third or fourth 
garage door in the UK.

Another option would be to build up the parts as you have done, then 
have someone TIG weld the pieces together.

Best regards,
