avia | A question of business

So, I am thinking that I might start to do a small business type thing, making patches. The kind that you sew on clothes, or, you can pin them on. They are going to have various neurodiversity type statements on, because, I don't see a lot of people making patches/buttons for actual neurodiverse people, more like cure stuff. I also want to make therian/otherkin/non-human ones, and, similar things that not typical people might want.

(A lot of these, it's meant to be "communication patches", you put them on your clothes/bag/etc. and you can point at them when you don't wish to speak but you have something you want to say.

simply one that says, Autistic Pride with a rainbow infinity symbol
also, therian/otherkin/asexual/etc. pride ones
“Neurodiversity (in small font: “has no”) Rules”
“I have a right to exist”
“Not making eye contact doesn’t mean I’m a liar”
“I don’t feel like talking right now”
“Please don’t touch me”
“I’m concentrating, don’t interrupt me”
“Not everybody speaks with words”
“Not a native speaker of any language”/”Language is not my native language”
“I speak fluent emoticon”/”I speak best in text”/”I speak fluent kaomoji”
“Stimming IS a language”/”Flapping my hands IS communicating”
“I spend my whole life trying to learn your languages… could you even try to learn a little of mine?”/”I spend my whole life trying to understand your world… could you even try to understand a little of mine?”
“Do not pet” (based on the service dog ones, it could make people laugh because, people do act like they can just pet and touch people sometimes… I want one that says “Do not pet the swan” in particular….)
“Don’t assume I’m not happy just because I’m not smiling”
“I’m not trapped in my own world, I choose to live there”
“Noise hurts”
“Keep calm and stim” (I think, the “Keep calm” trend is a little used too much but, it would be funny in this case I think!)
“The eyes are the windows to the soul. You assume I want to look at your soul.”
“My body is not your property” (I would like this for a general rape/harassment awareness button too!)
"The internet is a part of real life"
"The internet: a place where deaf people can speak and be heard"
"Text IS speech"

I got some blank patches and, I have some iron-on transfer paper that is left from another project. I also want to put charms, beads, etc. hanging from the bottom, and, I want to do custom versions.

For each patch, what I will need is:
- blank patch (they cost $1.50 each)
- transfer paper (I think that for $10, I can get about 10 sheets, cutting them into pieces will give me enough for about 100 patches so, it's 10 cents for each patch)
- two safety pins for people who want to pin them on (didn't look at the price of this yet)
- charms and jump rings (I have some jump rings, I don't have charms, the charms will be most expensive. I can probably buy a large box of various beads for not much money, but, for special charms that I want to do, like a paw charm for a therian patch, it will probably be about $2 for each charm)
- shipping cost (about $2 to America plus enveloves?)
Total: about $2 for regular patch, $4 for special charm patch, $4/$6 with shipping

So, I am trying to think of how to make this make actual money for me. I don't want to charge a lot, but, at the same time, it will be hard for me to make anything if I don't charge at least $5+shipping for the special ones.

My questions to you are:
- What do you think is a good price for special patches (with charm that matches the patch)?
- What do you think is a good prince for regular patches (would just have beads)?
- Do you think it's fair to charge more for patches with different special charms than the regular ones? Or, maybe I should make it all the same price (meaning that the regular ones are more expensive) to make up the cost of the special ones by selling regular ones?
