Here is a basic sales script for marketing consulting services:

1. Introduction: Start by introducing yourself and your company, and briefly explain what your company does.
2. Qualifying the Lead: Ask the potential client about their business and marketing goals to determine if your services are a good fit.
3. Problem Solving: Identify the challenges the potential client is facing with their current marketing efforts and explain how your services can help solve those problems.
4. Presentation of Services: Provide a brief overview of the marketing consulting services you offer, highlighting the specific benefits and results you can deliver for the client.
5. Case Studies: Share examples of successful projects you have completed for other clients in a similar industry or with similar goals.
6. Handling Objections: Address any objections the potential client may have, such as cost or timeline, and provide solutions to alleviate those concerns.
7. Closing the Sale: Ask for the sale, and provide a clear next step for moving forward, such as scheduling a follow-up call or meeting.
8. Follow-Up: Follow up with the potential client to ensure they have all the information they need, and to see if they are ready to move forward with your services.

Remember, the goal of a sales script is to have a structure for your conversation and to help you stay focused and on-track, but it should also be flexible and adaptable based on the unique needs and concerns of each potential client.
