I tend to get offers for new projects from past customers, as well as them telling me about their business buddies who need a project done. With that, I know whom to email when I have unsold time coming up.

It really is a sellers market at the moment, so you can probably just call up random mid to large companies in your area and ask them what kind of projects they are trying to hire for.

If the thought of that makes you uncomfortable, your best bet might be to team up with an agency so that they'll re-sell you at a higher rate to their customers. That tends to cost you 20% of the project gross, but if it is a profitable project, that price of admission might still be worth it.
