Brannon - I would say yes, have a piece of property to go along with the design. As you know, not all designs can be built on every piece of land, so I would gather several lots currently on the market to suggest to your client. And I would also team up with a broker, or brokers who regularly sell land and show them what you can do for their buyers. I worked a development at the beach selling lots to clients without the help of an architect, and the prospect of figuring out just how to build that dream home was often what prevented me from selling the land. My clients needed help with a builder and architect to make the decision on the land. If you have the funds you could buy land and package a design with the lot and list the package for sale. Without land you can't really "list" the designs for sale through a real estate broker. But you can team up with brokers to bring you referral business. If you pay them a commission for this, it needs to be disclosed to the client. I'd also pull in a good builder so that you have the entire package ready for a client interested in building their dream home. The easier you make it for the client, the better.
