a) You can design and make it; I can't. I have basic electronics knowledge and that is definitely more advanced than anything I'd get done in a reasonable time.
b) Speaking of reasonable time, it'd probably take even you more than $50 in time, material and parts (mostly time) to make this. This doesn't look like the kind of PCB that you'd hand-solder either, bringing us to...
c) Making 1000 of something tends to be cheaper per item than making 1 of something, and I'll gladly take an option that's not only cheaper than anything I could make myself, but also ready to use.
You definitely should share your PCBs by producing them at scale if you're willing to do that.
