Add Custom Sticky “Request a Quote” Button to WordPress Website

I’m looking for an experienced WordPress developer to add a custom sticky “Request a Quote” button to an existing website. The button should: Appear properly on both desktop and mobile Stay visible while the user scrolls Have a clean, professional hover/entrance animation Match the existing website design and branding Link to the existing Request a Quote page/form Be fully responsive across different screen sizes Not interfere with other website elements Be lightweight and not negatively affect website performance The website is already built, so no redesign is required. This is a small and straightforward task for someone experienced with WordPress, CSS, and responsive development. Please mention how you would implement the sticky button and share one or two relevant WordPress examples if available. I’m looking to get this completed quickly.
