Have you thought about making your own pcb's using a 3D printer? If you don't have a 3D printer maybe you could partner up with someone who has one that would be willing. Ohhh, I don't know who but maybe the guy who's post is above this post might be interested. Baahhhhhh!

Wish it worked like that, but sadly no ;) Milling PCBs also won't work on metal core substrate as you can't control the depth enough to not cut through the insulation material and into the metal core (though works fine for copper clad fiberglass).

I use China for prototyping (... you can't beat the cost), but move to a US manufacturer for the metal PCBs once I have something nailed down. The thermal performance of the US brand-name metal core materials is a lot better than the Chinese budget stuff (though you could get it made there as well).

I know you have connections and the materials and all of that,but how much would the array cost you built in the start of your new thread ?

Realistically, qty 10-50 metal core PCB from China (single layer) will run you about $50-80 shipped, depending on the number of square inches of the bounding box. No one will sell you one :)

Really varies. Loading new LEDs on an existing board is not an issue - the PnP is already all setup so it’s a matter of switching some feeder slots around.

I like making new boards for sport if they’re not totally crazy. I usually don’t charge if I think it’s viable as a more general appeal product or if I want to try a concept out. I can’t load and assemble or even procure the parts at anywhere near the cost of direct-from-Shenzhen though.

If you’re interested in the pricing dichotomy consider an inductor I use on my LED drivers. The Abracon part is a $0.40 in quantity, the equivalent size and shape and similar spec Chinese Sunlord part is... $0.06 in quantity. This pricing structure of course doesn’t hold for name brand Cree/Lumileds parts, unless they’re bottom bin or fakes.
 
This really ideally what I am looking for,there was just schematics for it not price:
