Can you provide more detail on the ceiling business? From a general standpoint, if one is entering or inheriting an already successful business, find new product for existing clients and expand on that. Focus on the process within the business and find new ways to grow the business to bigger than what it currently is. Expanding the business is probably the best way to grow a ceiling business. Raise the ceiling! If it's a one stop answer type of business, you would want to focus more on marketing and social media for new customers.
