WordPress Website Pop-Up Optimization

Fix and Improve Pop-Up on WordPress Website

I need a WordPress developer to resolve a loading issue on my website, (http://gatewaytax.ca), caused by my pop-up generator. Additionally, I’d like you to review the current plugin and recommend a better alternative, if available. The goal is to have a pop-up that:
- Works seamlessly without affecting website performance and page loading.
- Appears only once when a user first lands on the site and doesn’t reappear unnecessarily.

Tasks:
- Fix the current pop-up conflict.
- Recommend and implement a reliable, user-friendly pop-up plugin (within a reasonable price range).
- Ensure the pop-up is functional and optimized for user experience.

Requirements:
- Experience with WordPress and plugin troubleshooting.
- Quick turnaround and clear communication.
- Fully functional website with no loading issues.
- A working pop-up that meets the described requirements.
- A brief explanation of the issue, the solution, and the chosen plugin.

- **No phone calls, please. Applicants who call will be disqualified.**
