What free stuff do give to get leads?

Perhaps you're in the business of selling your services. It can be a bit tricky to turn, say, freelance writing or marketing consulting into a physical product. But with a little bit of creativity it's possible to make a product out of an intangible service. A great example of this is the freelance proposal template you can download for free from this content marketing specialist's website. In exchange for a battle-tested proposal template, users give their contact information away, and assuming they like the product have the option to come back and purchase classes or sign up for consulting in the future.
