If you have two paying customers it means you have something people want. Congratulations! That means you actually have a business. Now, all you have to do is keep growing and improving. One thing I would do is reach out to those first customers, and thank them for being early customers. Ask them how you might help them even more, and why they found you valuable enough to buy. If you can find out more about them, then you should be able to find more people like them, and target your marketing to them. Good luck!
