I am trying to find out what I need to get a grant to start a business. One of the things I need to figure out is "How big do I need my building to be"? I was thinking of going with a 300' by 300' 2 story building so I can do the pop-up archery upstairs and a smaller range downstairs for tuning bows. I would also like to do sales and sevice in the downstairs portion. Would this be too big?? Someone told me that a building that is 300' by 120' would be plenty big enough. What do you guys and girls think is the right size??? Let me know and this would help me out greatly.
