Personaly I would have left the skin on which helps regulate the temp of meat from going from warm during the day to cold at night(speaking fall temps) . To protect it from freezing you could store it in a cooler as said. Just don't let it sit in Blood/water. When I butcher my deer I take the deboned cuts and partily freeze them to make cutting into individual cuts easier and more profesional looking. I think you'll be fine, next time don't skin it till you butcher it.

Good Luck.
Ps Also some sausage companies buy meat in bulk when they can get a good price, freeze it, then when they need it they partialy defrost and use. Sell the product to you, then you take it home and freeze it till you need it. I do the same, freeze big chunks and cut up and use through the year as needed. Ie Burgers, then I refreeze the burger patties. I usually make between 12-20 burgers at a time. This way the meat stays fresher in chunks even though their vacuum packed.
