Like a lot of others have said and what I have experienced with three archery shop owners who I know quite well,it will put a severe damper on the time you have to do what you love,and has already been stated you are competeing with the box stores,catalog stores and internet sites.I am sure you could make it work with very long hours and tireless customer service.Personally I am to selfish in that area of my life,I am always looking for more time to hunt not less.
Maybe mail order or ebay would be a way to involve yourself with out having it run your life.
