Help me grow ( I will not promote)

I created an app that help service providers—beauty salons, pet care, home maintenance, auto services, and more—get discovered, manage bookings effortlessly, and grow their business. Customers can easily find and book trusted professionals, while businesses streamline operations with appointment management, direct messaging, and real-time updates—all in one app. No setup fees, no hassle—just growth. But after deploying app to App Store, now I came to halt on how to market to business owner because without business owner none of the customers can use or can see anything in the app.Can anyone help me share their honest opinion and help me stay motivated to keep on going forward.
