Some people dread asking their families and friends for help when it comes to networking or marketing
. If you really don't want to get them involved, at least ask for good leads from them. It won't hurt if you introduce them your business. You can still do that without inviting them to join. Who knows, but maybe just by showing them your website, they will be intrigued with it enough to spring the question of how to join the program themselves. Don't shun yourself to all the possibilities. Think outside of the box. Get out of your comfort zone. That's basically how rich people made their money.
