It sounds like you are looking to build an automated system to book appointments and make sales based on engagement at a tradeshow.

Here are some steps you could take to create such a system:

1. Determine the criteria for engagement: Before you can automate the process, you need to define what counts as engagement with the show. This could include watching a certain amount of the show, commenting on a post about the show, or interacting with a social media account associated with the show.

2. Choose an automation tool: There are many automation tools available that can help you automate the process of booking appointments and making sales. Some popular options include Zapier, Hubspot, and ActiveCampaign.

3. Set up triggers: Once you have chosen an automation tool, you can set up triggers that will be activated when someone engages with the show. For example, if someone comments on a post about the show, you can set up a trigger that sends them an email with a link to book an appointment.

4. Create a booking system: To allow people to book appointments, you will need to create a booking system. This could be a calendar tool like Calendly or an appointment scheduling app like Acuity Scheduling.

5. Follow up with leads: Once someone has booked an appointment, you can use your automation tool to send them follow-up emails and reminders about their appointment. You can also use the tool to track their progress through the sales process and follow up with them as needed.

6. Measure your results: Finally, it’s important to measure the success of your automation system. This will allow you to make adjustments and improvements over time. You can track metrics like the number of appointments booked, the conversion rate from appointment to sale, and the overall ROI of your automation system.

By following these steps, you can build an automated system that allows you to book appointments and make sales based on engagement at a tradeshow.
