I am looking to buy/download a professional level (used by big corporation i.e. BBC, CNN, RT) news platform that can be used to build a high-grade news website. I have done some research and all I stumble upon is a range of WordPress plugins and some low quality scripts written in procedural PHP.
Are there any professional platforms on the market I could present to investors to ensure that my proposal is serious?
I am open to languages, but I prefer, although do not limit my options to modern frameworks like angular, react, riot, etc.
