Build your trapping supply line to your target. If you are going to run a 1 farm line, you dont need much get started, a few #2 foot holds for K-9s, a few snares and if you have a water supply with rats maybe some 110s and 160s body traps and a few colony traps. Trapping a long line is a little more involved. My K-9 line is now 100% snares , my coon line is 100% DPs and my water line is mixed with 50% 110s and 50% colony.
Most of the videos make it look a lot harder then it has to be. I will tell you like I tell every person I have ever helped get started, Find someone close to you that will let you tag along for a day or two and see if its for you. Most of the time you can find trappers that will even loan you some traps to get started. If you already have a place to trap, find someone that will come and help you set it up for the first time.
As for selling fur, there is always a market. This depends on what you want to put into it. I myself have built up a market out side of the fur industry. I will still sell some on the fur market, but there is more money for most of your take in the private market. In Ohio you can keep fur after season as long as you let your GW know what you have. By doing this you have all spring and summer to Tan, Clean, and Mount what you have taken over the season.
A good example of this would be some of your color phase animals. If you run a black coon ar even a blonde coon thru the fur sale, a lot of the time you will very little for them if you dont have more then the one or two cus the buyer dont want to have to match colors with diffrent lots. Sell that same black or blonde coon on Taxidermy,net for 4 to 6 time the money. Another example is your coyotes. Sold thru the fur sale will bring $20 to $30 tops. I have buyers that pay $75 for the tanned hide, $40 for the cleaned skull and $1ea for toe nails. If you have one with a bullet hole in the skull, you pull the teeth and sell them for $4ea.
I just finished a tanned beaver that if sold on the fur market would have sold for $25. I tanned it, Put it on a grape vine ring, added a few Turkey feathers and sold it for $360.
There is a BIG market out there, you just have to find it.
