Build Android and iOS Apps for an Existing WordPress Website

I need an experienced developer to create Android and iOS apps connected to my existing WordPress website. The website contains several sections designed for different e-commerce and content purposes. All existing website content, features, and future updates must automatically synchronize with both apps. I should only need to upload or update content once through the website. The apps should have a classic, professional, colorful, and vibrant design. They must also be straightforward, user-friendly, and easy to navigate—not unnecessarily complicated. The project must include professional app-style navigation, testing, submission to Google Play and the Apple App Store, source-code ownership, basic training, and post-launch support. Please include your estimated price and timeline, along with examples of similar apps you have completed.
