Being a trapper involves many things. One of them is preparing pelts. It's almost an art form and it isn't that hard. But, as with most things, you get better at it the more you do it.
Costs to prepare pelts are minimal. A knife, a form, a scraping tool and you are in business.
If you are only going to trap a few animals, there is even more reason to prepare the pelts. They can turned into wall hangers, gifts or garments.
My 2 cents: starting out trapping to catch coyotes, which can be a challenge, only to dump them doesn't sound very rewarding. Learning to catch a coyote and process it and being able to show off the pelt or being able to say "I got X dollars for it sounds better.
A compromise could be to sell on the carcass if such a market exists in your area.
