Leads should come in the form of people that are likely to work with you. When you get leads for free, they may not be targeted. That’s okay though, you can target these people yourself, and it’s free to do if you’re willing to put some time into learning marketing. Don’t just get a logo slapped together and act like you’re an awesome company with all kinds of things you don’t really have in place. However, you can work with leads that you target by learning to make a splash in places like review websites and other places people read more about companies.
As a last resort, you could try cold calling by phone. This is probably the most depressing and soul destroying activity on the planet. Even if you get past the usual questions such as ‘If you’re selling something – I’m not interested’ and ‘How did you get my number?’ you need a really slick and professional script and the ability to recognize and avoid lonely old ladies who just want to interact with someone, anyone, in fact.
