Theme Installation & Configuration on VPS -- 2

I need an expert to upload my next.js script purchased theme from Codecanyon to my VPS hosted by Prohoster. After installation, I need you to configure the SMTP settings to ensure smooth email communication. Additionally, there are standard customizations that need to be done for the website to run seamlessly. This includes some minor design changes and functionality enhancements. Lastly, I need you to add whatsapp OTP

Ideal Skills:
- WordPress theme installation and customization

Experience with Prohoster and Codecanyon themes is a plus. Please provide examples of similar projects you've completed.
