Configure Nivado Theme Seamlessly

I have already installed the Nivado theme on my WordPress site, but everything still looks like the old Construction Field template. What I need now is your expertise to switch the front-end over correctly—starting with the homepage, which is my top priority but I also want to create new pages with the same Nivado look—while making sure every setting in the dashboard is intuitive for future edits.

Your job is to:
• Import or rebuild the Nivado demo layout so it replaces the existing look without breaking any current pages or posts.
• Tidy up menus, widgets, and theme options so I can swap text, images, and colors in a few clicks.
• Recommend and install only the essential plugins that pair well with Nivado (performance, security, SEO), or explain why none are needed.
• Hand over brief, clear instructions or a quick screen-share so I’m fully confident managing updates myself.

I’d like to see examples of sites where you performed a similar “theme switch-over” and a short note on your WordPress experience—especially if you’ve worked with Nivado or a comparable multipurpose theme. Let me know roughly how long you’ll need, and we’ll get started right away.
