First, if you haven’t already done so, make sure you install the Contact Form 7 plugin: http://wordpress.org/extend/plugins/contact-form-7/ With it installed, go into the settings and make a contact form for each agent. Make sure each agent has their own email address set for it.
When you create the contact form for each Agent, up top you’ll see a “shortcode”. You need to copy that shortcode to the clipboard because you’ll need it in the next step.
Now create an Agent: To create an Agent, go to the left column of wp-admin and click on Agent -> Add Agent. For the title, enter the Agent’s name. For the content, put in some bio text for the agent. And under that, enter phone, fax, email, etc.
You add an Agent “image” the same way that you do for adding images to a Listing. Click on the “insert/upload image” button. Upload a single image to represent the Agent. When you’re done, exit the window by clicking the “X” at the top right.
In the Contact Form section, paste the shortcode (from Contact Form 7) that you copied to clipboard. Remember, each Agent will have their own shortcode.
Add more agents the exact same way. Now, when you make a Listing post (or edit one), there is a dropdown menu to choose an Agent. That’s all there is to it!
Create a “Page”. Give it a title like “Our Agents”. Add some content if you want, or not.
Give this page a Page Template of “Agents”, then click Publish.
Now add it to your menu bars by going to Appearance -> Menus. Add the Agents page that you created to the menu and drag it in position. (For detailed information on creating menus, see the video in the Getting Started page)
