This is pretty easy to do to be honest, hire someone it shouldn't be too expensive .
I personally do account monitoring for other endpoints such as new posts but not really for stories as most people aren't interested in that , but it's the same principle .
Do not fall for the error of implementing a solution that depends on a single account to do it (such as the chroime extension suggestion) , you will regret it very fast .
I am not sure exactly what you are trying to accomplish here but I assume you want to use the stories for reposting content or something similar ?
So I am also assuming you don't want to do this for a single account but would rather have the possibility of monitoring multiple target s at the same time .
You should definitely aim for a scalable solution that will allow you to use multiple accounts with proxies to monitor multiple targets simultaneously .
Even if you were just monitoring 1 account it's still recommended you use more than 1 account to do the scraping, instagram scraping is a constantly evolving game and there's a fair chance the account you use might get flagged easily if all it's doing is scraping the same account over and over again every day ...
