Expert Web Developer Needed for Hostinger Website Fixes and Configuration

I require a skilled web developer to address several outstanding issues on my existing website, which is currently hosted on Hostinger. The previous freelancer left some problems that need attention. This project focuses on small fixes and configuration adjustments, not a complete website redesign or advanced marketing services.
The main problem is that my website barely appears on search engines in France, and Hostinger has informed me that several important tools and features included in my hosting plan are not being properly used or configured.

Also fxing the functionality of the WhatsApp contact button and the Google Maps integration on the website.
Replacing the current company logo with the correct version.
Thoroughly checking and ensuring the website is properly configured for optimal performance. Implementing necessary adjustments to help the website appear correctly and improve its visibility on Google and other search engines.
I am seeking a freelancer with proven experience in website troubleshooting and familiarity with the Hostinger platform to efficiently review the current site and resolve these issues.
