Am I the only one that thinks $900 seems like a deal? As a business owner I know about what it takes to produce a product.
Lets see, answer the phone and reply to multiple calls and emails about pricing, the process and other anal stuff.. 1-2 hours of your time. Receive the head and cape, client decides to talk your ears off for two hours, 2 more hours of time, spend time ordering foam forms, eyeballs and all the other shit you need. 1-2 hours of time. Package up the cape to go to the tanner and arrange everything that goes with it. 1 more hour, more if they actually do it themselves. Put the mount together, put the cape and antlers on and off again multiple times and make changes to the foam form until it's right. Who knows how many hours? Sew everything up, paint whatever needs to be touched up, get the fur laid out just right.. a couple more hours.. call client to let them know it's ready. A few minutes unless the guy talks your ears off again. Client picks up mount and talks for another two hours..
By this point you've got 20-25 hours in to the thing, subtract your shop costs like heating, electricity, water, accounting, insurance, the form, eyes, consumables and so on and that $900 is now down to $600.. divide that by the 20 or more hours and you've now made a whopping $30/hr.
