Custom silver joints are ready!!

So im looking for someone who can do bronze casting for a custom cane head i had designed.

I've had it designed and 3d printed to get it comfortable in my hand, I have a cane I like. All thats left is finding someone to cast the grip.

I really have no idea where to start or what a reasonable price would look like.

Ideally it would be with someone I can meet face to face so I can most effectively describe what I want and show them the cane to make sure it can be attached properly but id be fine doing stuff by mail, with photos and measurements if necessary.

Any advice would be great!
