How Do You Get Commission?

Need some suggestions from creators doing commissions and people who order the commissions!
I'm thinking of open commission, but don't really know how to start with
I see people using Patreon, Fiverr, and Ko-fi, but I don't really know how do they work
Is that you guys buying the product on Fiverr, Patreon then the creator will start to do it in a schedule duration time?
Do we have any guarantee about the final product with those sites?
I believe I spent much times and knowledge in this LoRA training field, and I want to get some extra money with it by challenge myself with different kinds of commission
If I success with this, here is what I'm gonna do:
1/ Patreon:
Get support and request a LoRA depend on the tier each month
Image request
2/ Fiverr:
One time commission without subscription
3/ Directly method:
Pay directly to my Paypal, or any kinds of personal account (bank, financial apps, cryptocurrency, etc)
Benefit of discount
Payment: depend on how complicated the commission
$15: a pose/expression with upper body only
$20: general concept/full body pose/scene reference, parody that has only 1 character in the frame
$25: multiple scenes LoRA, 2 scenes, add $5 each scene, this should be less than 2 characters in the scene
$35: scene with above 2 characters, max at 5 characters (I don't believe current checkpoint that run locally can do more than 5 characters accurately)
Half-fee or free if requester have a good dataset to start with (only apply with directly payment method)
What is general concept?
Ex: holding a specific object/a kind of action/animalization/objectification
Rule:
Will think about it more
SFW, NSFW, fetish: I'm okay with it
Only proceed the commission if I can get enough data (minimum at 5 images)
The less the dataset is, the higher overfit, so you have to accept it, I'll try my best to limit it
Only train directly on based checkpoint, ex: Illustrious 0.1XL, NoobEPS1.1, NoobEQ1.1, etc
What do you guys think about this? Is it expensive or cheap with the price?
I wonder how many interested in a commission of concept, seem like it hard to get interest since we only gen it for just couple times?
Please give me some suggestions, this will help me a lot :D
Thank you
