Prices for toll processing trim to shatter/badder

Curious what you guys think a good price to charge for tolling someone’s trim to badder or shatter would be in LA?

I’m aware most people do a 50/50 split, but I’m more curious what you guys think a fair price is for both parties when running it for a toll? Charge by the lb of material processed or by the lb of material produced?

Also I’m not sure if this is in the right category so maybe someone wants to move it for me.

Thanks all
