$1 per minute retail for cutting time. All other aspects of the job are $60/hour with a minimum of $30. I do offer some hourly rate diswcount for wholesale customers depending how long I've been working for them. If the job is big enough I will price in a bit or two. For large wholesale customers I do it by the job after figuring out how long it will take to cut a sheet. I give them a break off the $1 per minute run rate of the CNC. I have a spreadsheet that I can use to plug in different discount rate percentages depending on how large a run the customer will be doing. It's worth the time to put this spreadsheet together for larger jobs.
