Get a new client. a client that understands the value of leads in general and the high value in your live phone call leads. If you have to sell someone on the idea of leads, you're targeting the wrong people. Right now, there are way too many people that need/want leads and will appreciate the high quality you can deliver on. Focus on those people.
Put another way: FIND your client, NOT create your client. Once you get built up enough creating clients may be worth your time, but you'll be so leveraged with employees, it won't matter to you.
