INterior Fixtures for Fun and Profit

I've been trying to be a bit more strategic about business operation and one idea is to develop things that I can mass produce and sell cost-effectively. These house fixtures: shelf brackets and curtain rod brackets is thus. If any of these designs appeal to you I can give you a quote!
The raw ingredients below:

The finished product. In more recent versions I have switched to plug-welding the plates from the backside so that they don't show.

I have access to a lot of worn out disc brake rotors through my bike shop job, so I've been turning them into artsy-fartsy shelf brackets.

These have two quadrants of rotor overlaid on one another to create a really cool visual effect.

The tree-branch theme is something that has interested me for a long time. Here is a big run of tree-branch shelf brackets that I made recently.

These ginko leaf curtain rod holders are sort of experiemental. I don't know if they're gaudy or pretty when installed.

I'm no ichthyologist, so if you are, hit me with your critiques of my osteichthye anatomy. They are no specific species, but based on sketches made from various photographs.

I got this beautiful piece of walnut and felt that it would be a good compliment to the tree branch theme idea. This corner shelf was for my partner's birthday.

The disc brake rotor brackets work as bookends too! I might make some with heavier bar stock to serve better in this capacity. Life before death.

I did some number crunching on the estimated time spent making a batch of twenty of each kind of bracket in this post to figure out a price to put on here. Here's what I came up with. Prices do not include paint. I can rattle-can spray them, or have them powder coated for a really durable finish. Also can make them out of stainless if desired for an upcharge, of course:
