Congrats on developing a SaaS with revenue . . . keep bootstrapping . . . you don't need investment.<p>Polish up your app and code . . . there are some rendering issues on initial load and validation on the login form. Test, improve, polish provide the best UX you can to keep existing customers.<p>Start a blog with articles on how realtors can use social media, publish often and collect emails/build a list, email that list valuable information and details on PropertyWizard.<p>Invest some of your revenue in contacting realtors, test out some ideas and see what your ROI is. Try calling realtors in person make a goal of 1, 5 or 10 per day, approach an office with 50 realtors and offer them a group package, test mailing out 100 postcards, track the realtor/office names/provide a unique URL and track signups. Find out what's working to generate signups and focus your efforts there.<p>Add a signup process on the site (checkout stripe), test three subscription levels, offer a annual discount sign up for 12 months (price of 10). Add an Office package up to XX realtors, email us for custom plans/more realtors. I think focusing on real estate offices with multiple agents might be a good way to grow your subscribers.<p>Add a favicon, minor but I always notice when they are missing from a site.<p>Don't sell a piece of your pie at this point, keep growing it.<p>Good luck, update us on how it's going.
