Buy a book a learn to do it yourself. Its not hard just a bunch of handwork.
The way that we do do it is a chemical tan with alum.
a pint of alum in a bucket of water deepnenough to cover the hide.
1. Flesh hide
2 soak in alum and water for 3 days
3 take out of bucket and let dry
4 work hide until soft across a piece of metal. I use an old garden hoe with the edges rounded off.
5. Sand the leather until white
6. Rub down inside with a leather conditioner and turn inside out or lay flat however you skinned it
I dont do coyotes because I hate fleas and ticks but I have done a bunch of deer.
