How much would you charge

Not saying that this is true ... lets just say more of a figment of my imagination...

So if a guy came to me and he wanted to make a thc infused glycol for use in e -cigs (he pry didnt but lets just say he did) ... basically i would make bho then mix it with pg and he wants batches made from 15 ounces dried flower (so each batch would be me turning 15 oz dried flower into pg thc solution) how much would you charge to make each batch for this imaginary guy who really never asked me to do such things...

Its not about what I would charge..
I know my herb equals out (including all yearly costs/bills/nutes etc etc ) to 37¢ per gram
I make quality qwiso hash. And I do mean quality, yields a white powder..a pint of 99% iso costs me $1.18 and will run a couple ozs

Basically what I'm saying is...figure up your costs and how much you have to charge to make a profit..like any other business/drug deal
Then determine how greedy you want to be

if I were to be filling ecig tanks I would be getting $30 per ml. hypothetically of course. and that would be for 1x strength. hypothalamusly if it were 2x I would be getting $45 per ml. If I were to do his I would use bho mixed with pure pg usp

hypothalamusly lol
