Mine doesn't want a deposit. He wants full payment when it's done. When I drop of several animals, I usually pay for the tanning when it's done, which is deducted off of the final bill. My previous taxidermist wanted a deposit big enough to cover tanning and price of the form. I would also make payments towards the final bill to lessen the impact when it's done. I'd just drop by and give him a hundred bucks, or more when I had the cash. For pets, he would require full price upfront because half of the time, the people would never come back to pick them up. He had quite a collection of cats, dogs and parrots.
