Make a large part of the commission dependent on how close to the initial estimate the final price is. This will ensure a more accurate initial estimate and counteract the incentive for the agent to sell quickly cheaper (instead of waiting for a better price.)
Many times you go to a website to check what they ate offering, but it’s not very clear what they do. It may be because what they do is complex, or they rather sound clever than do a good job communicating what’s important to you.
Have a website dedicated to explaining exactly what other service providers do. In a simple and straightforward way, the reader will learn the important points they want to know about that service. There can also be a discussion by the readers for each such service explanation.

By looking at the demographic and psychogenic markup of your current customers, you can find out other things that a large part of them are in-market for. Things that interest them or they are looking to buy.
You find such an interest area that does not contradict your brand, and find good partners in that field. Invite these partner(s) to do an event with you at your store.
Your customers will appreciate it (the large group that is interested.) The partner will like the new business and clients they get. And you’ll get a commission on sales from the partner.
