I'm looking forward to seeing how it turns out!
I'm not sure if you are new to sausage as whole or just this one. If new overall, I would suggest that after you mix up your seasoning you fry a small amount (just a 2 inch glob) and see if it is too salty, too bland, etc.
If it is good to go at that point you will save yourself some grief of a too salty/too bland experience. If not good to go, then add more seasoning if needed (or salt) or add more meat to dilute a heavy salt flavor. It's good to plan to be able to do this or season conservatively for a pound or 2 and then adjust until you got it sorted out. You would want to know how much you are adding per pound and write it down.
This is something to do with each new sausage and take notes so you can easily repeat a "by weight" measured amount of seasoning per 1 pound of sausage. The volume (teaspoon/tablespoon) measures don't scale well at various weights where the "by weight" measurement of seasonings don't ever go wrong :D
Also, don't worry if it doesn't taste the way you think it is supposed to taste. The flavor will change when the finished product is done.
The key is that it simply just taste good and isn't too salty or too bland :D
