BE CAREFUL!! Make sure you consider: Material handling expenses (forklift rental, time shuffling sticks, bundling/banding for shipping); timber cleanup time, finishing, planing if desired, chamfers, etc.; time spent doing fit-up, re-cutting the piece with the extra mortises. Depending on the size, complexity and finish work desired by your customer, the non-cutting portion of your work can easily exceed the the cutting portion. Then there's the raising. I did a frame that ended up at about $70 per joint (tenon= 1 joint) which included planing, sanding out planer marks, chamfers & oiling and raising (but NOT the cost of the timber). In the end, the customer was pleased with the product and the price and I didn't lose any money but didn't make a killing either. Good Luck. I'm interested in the outcome!
