Any profile that kills beasts will work out for you - just check the leveling packages.. There's no reason to make any specific skinning profiles as you can find some very suitable in the leveling section. To find out what level the mobs have to be, take your skill level and divide it by 5. Say your skinning is lvl 175, you can skin mobs of level (175/5=)35 - look for a leveling profile of that level.
