WordPress Sports Agency Website Modernization

We are seeking an experienced WordPress developer/designer to modernize our existing sports agency website while keeping WordPress as the CMS. The project includes refreshing the overall design and user experience, updating the homepage and existing page layouts, improving mobile responsiveness and navigation, and modernizing player/athlete pages. We also need updated photos, graphics, and content incorporated while preserving existing URLs, SEO, and Gravity Forms functionality. Changes should be built and tested on a staging site before launch, and the final site should remain easy for our team to update internally. Please share examples of similar WordPress projects, your experience with Gravity Forms, and your estimated timeline and cost.
