The opposite of "big-time operators" would be "small-time operators" or "amateurs". These are individuals who do not have the financial or professional resources to compete at a high level or to exert a significant influence in their field. Small-time operators may lack experience, expertise, or a large network of contacts, and as a result, they may struggle to make a name for themselves or to gain traction in their industry. While big-time operators may be seen as sophisticated, powerful, and successful, small-time operators often face challenges such as limited resources, lack of recognition, and fierce competition. Nonetheless, with persistence, passion, and hard work, small-time operators can achieve success and make a meaningful impact on their industry.
