Flutter App and Website Setup

I already have a complete Flutter code-base and a live hosting account; the remaining work is to put everything in place so the solution runs smoothly everywhere it is meant to. Concretely, I need the project compiled and deployed for both iOS and Android, plus the companion website installed on my existing server.

Your job ends once:
• The app is built with the current stable Flutter SDK, signed, and ready for TestFlight and Google Play internal testing.
• The web panel (or landing site) is uploaded to my host, environment variables are set, and a quick smoke-test confirms all API calls succeed.

No feature additions or code changes are required—this is a straight installation and configuration task. If you have a reproducible CI/CD approach (Fastlane, GitHub Actions, Codemagic, etc.) that will speed things up, feel free to use it, but simple local builds are also fine as long as you document the steps.

Please share a brief outline of how soon you can start, the tools you plan to use (Xcode version, Android Studio, Flutter channel), and any similar launches you have handled before.
