someone replied with getting to know vendors in the area, though its a good idea, its not a business plan. There are downloads online to get templates but I'm apprehensive on using them. Once I get started, I just get lost. There is so much to think about and so much I have no idea to think of. SO overwhelming! I have a friend launching a photography business, but he didn't write a plan, he just dove in... So he didn't have advice either!!
Good luck to you!
