become familiar with your target market..who you want to sell your product to..example, kids, teens, young adults, males females..also research what type of sunglasses are in style, make surveys..build a website and post your ideas. promote it everywhere you can..make a business plan! how much money are you going to start with, are you going to have a location or start off online, who is your manufacturer going to be? where are you going to promote your new product? what will your prices be? why should people buy you product, how will they become confortable inverting their money in your sunglasses? research your competition! every detail counts when it comes to creating your own business. be creative and have fun! I love business!
