Mine is more of a mix between marketing and economics. For my headwear business I did a Environmental Assessment that includes all statsm, competition and just the industry market and how we can find our niche (19 pages). I also just finished a Marketing Plan for the same business with strategies we would use and how we would differ from the competition and our financial plan (27 pages). Talk to me if you want either of them, I will help a fellow NS'er anyday.
