yea i did the math took me to 36k per but would have to be worth it to me as well per charge like you said
Telamon provides single charge tubs for 6plat upon request. I don't think you'd get any customers unless you charge 5plat or less, but then you'd also be losing money. Maybe if you charge 36k gold per, which would allow those without plat to use your services and you still break even.
