Most taxidermist shops will flesh, salt, and ship your hide for you.
It's been a few years since I ran one through Dakota Taxidermy here in Bismarck (I don't know if they still help, or not), but it was about $270 for the full hide. And like I said, it's been a few years. I have also sent hides away using Nature's Reflections the past few years. They will flesh and salt the hides for you to make sure the hide is suitable for shipping and tanning.
Fun fact, a lot of taxidermists ship their hides in bulk to tanneries in Michigan. Due to the COVID, the Michigan governor shut down all non-essential businesses last Feb. This included tanneries. My taxidermist is still waiting on my cape from last year. Last I checked, he said it was still 10-12 weeks out way back in late Aug or early Sept.
