HOW TO LAUNCH A BUSINESS WITH NO MONEY
Market your startup and what you are offering through social media until YOU make enough sales to use this as your seed money. Ask everyone you know to tell everyone they know what you are selling. Get a beta group of friends to try what you are selling and give you testimonies. Finally when you make a sale get them to commit to telling 3 friends/family about your business. Create a movement of people helping your business get off the ground. Collect testimonies from day one and promote these online.
