Before you get started with generating leads you should take a look at what kind of cost per sale your model can support. After assessing your ideal cost per sale you can look at some realistic ways to generate leads. Make that list, then look at what you're best set up to convert when you play to your company strengths.
Quick example for you:
Lead source X has a cost of $50, convert 10% of a qualified lead to a sale has a marketing cost per sale of $500. If your average product sale can support that, that prospecting source should go in your list.
Take that list, sort it to playing in the order of your organizational strengths and test them in accordance with your budget and timeline goals.
Obviously a broad a deep topic. If you want to set up a call let me know.
