How to start working on creating a tool for monitoring and analyzing social networks?

Question

Monitoring

Hello Toaster!
There are many services on the network that parse news and form a rating based on the reaction of people in social networks: likes, shares, reposts / retweets, and so on.
For example, here are the resources:
- https://tjournal.ru/mediator
- mediametrics.ru
- https://top.st/
- mc.hertzbeat.ru/index.php
I would like to adapt a similar idea, but for a regional scale. To similarly form the top news within a city / region / region based on sites / rss-channels of news portals and regional publications.
Where to start such a tool? Where to dig? What to use? Is this a real task for one person? Or is it better to immediately draw up a TOR and give it to the team?
Questions on the other hand: how to evaluate this work? How much can it cost? If you know - do not pass by, please write a price range, for example, or even better - motivate?
Are there social media restrictions on parsing/analysis? Although, for example, social buttons on sites can easily read and show everything.
Or maybe there are already similar projects with source code?

First of all, you need to learn javascript to analyze the social network API, and then decide on the number of networks, the main language in which you will write the server (for sure, this project will not be limited to just js and html), and if you decide to give it to development, then experts ask for payment in different ways. the easiest way is to look at similar requests on exchanges to understand the cost
