Firstly, apologies if this is the wrong section, didn't want to tread into the other official ones and mispost 😃

I'm currently in the process of starting up a Kickstarter for D&D/TTRPG, and one of the rewards we're looking at doing is getting two of our boss creatures design and built out of LEGO/Blocks. This entire thing is brand new to me, I'm aware that there are folks who will design, build and provide instructions, however, could anyone give us any guidance on places/manufacturers to actually turn these into a bulk product and not just a one off design? Or if there is a more appropriate place/community to deal with this kind of thing.

Appreciated
Alex
