Responsive Navigation Menu Redesign (Match Competitor Style)

I need to make my website’s navigation menu fully responsive. The menu is already built, but it needs to be optimized for mobile and tablet devices.

Here’s my website: https://apkvip.site

I want the navigation menu to look exactly like the one on my competitor’s website: https://crazycubix.com

Important Details:

The website is built using a PHP script and is installed directly on my hosting (via the file manager).

All website files are located inside the public_html folder, and any necessary edits must be done there.

My budget is $15, with an additional $2 bonus for fast delivery.

I need the navigation completed and ready within 5–6 hours.

Only experienced developers who have worked on similar navigation designs should apply.
