Flutter News App Upgrade

I purchased the WRTeam Flutter News App: https://codecanyon.net/item/news-flutter-news-full-app/32062835
. Out of the box it works well, but I need two major upgrades:

1. Automatic News Ingestion

Integrate external providers like Alpha Vantage News, MarketAux, Tiingo, StockNewsAPI, Newsfilter.io, etc.
Articles should be fetched in real time, mapped into the app’s post schema (title, body, image, tags, tickers, categories).
Handle de-duplication, rate limits, attribution, scheduling (cron/queues), and provide a simple dashboard in the Admin to monitor ingestion.

2. Automatic Translation Layer

Any user can read article any language they want.
Use Google Cloud Translation API (or DeepL if you recommend).
Admin should control which languages to enable, with support for RTL languages.

3. Deliverables

Clean Laravel integration with queued jobs.
Admin UI for managing providers and translations.
Documentation on setup and API key configuration.
Unit tests and error handling.

4. What I’d like from you

Your proposed approach and timeline.
Estimates of third-party costs (API usage for both ingestion and translation ).
Any examples of similar Laravel or API integration work you’ve done.
