Answer:
small business
Explanation:
Based on the company specifications that is provided about Raul's company the most appropriate representation of his firm would be a small business. This is the case because a small business is categorized as any business with one owner controlling and running a business with less than 100 employees. Seeing as Raul only has 21 brokers employed and is planning to expand his model nationally but has NOT yet done so, then he is the owner of a small business.
