Use social media. Posts asking people to join your team won't likely produce results, but if you're clever, you can use social media to generate interest in your business and possible leads. For example, if you sell weight-loss products, you can promote before and after pictures on Pinterest or Instagram. If you sell makeup, you can post tutorials on YouTube that you share across social sites.
Networking, as it used to be called, is a pretty thankless task. The conventional approach to networking was to start with the network of friends and colleagues that you already have; friends and family, your existing clients, your contacts at the squash club and so on. Most people feel uncomfortable pitching to friends and family, unless you have an unbeatable idea or concept, but if that was the case, then lead generation would not be a problem
