There isn't really a way to just pull up agent statistics in our MLS. We can each pull our individual production and share that information with you. Some of the brokers have a BrokerMetrics which will show some of the numbers, but they typically use it to try to recruit agents.
I would love to help your boss out and list the property. You can take a look at my Trulia Profile and reviews and let me know if you would like to talk more. I market heavily on Trulia and if you click on may of the areas of Jacksonville, my info will most likely show up which means more exposure for your properties.
Please feel free to contact me if you need anything.
