If your company is interested in branding your listings with your logo, please complete the form you'll find at http://www.trulia.com/advertisers/brokers/. One of our representatives will then contact you with pricing information.
Please note however that this logo branding is geared towards large brokers and franchises. If you are an a smaller company I encourage you to check out Trulia Pro. It's designed with agents in mind. It provides you with your own spotlight ad (similar to a banner ad) and allows you to feature all of your listings within our search results. Check out the link below for more information and let us know if you have any other questions.
