Website and api

How much to build a version of this website? www.marketwirenews.com. Most of the data seems to come from feeds. We'd want the ability to have twitter linking as well as allow people to sign up for alerts for virtually any company that has a ticker symbol. Also, we'd want people to be able to link their Twitter account to ours and have it produce information that we send out. An example would be here - https://twitter.com/kRaZeY21_89/status/1483972344347598848. Finally, are you familiar with the Twitter API? I'd like to build out a Twitter profile similar to Market Wire News. Here's that profile https://twitter.com/MarketWN.
