I personally think Epic, Go Hunt, or HF are worth the $100 just to keep you up to date on changes in the different states and for draw deadlines. From what I've heard Go Hunt has the best filters when trying to find hunts you want to go on.
Another that might fit the bill is Toprut. They do draw odds. Not sure if they also have app deadlines or anything like that. if they do they would be the least expensive.
