Hello,
You can have the server where will be implemented the script, so it'll be running automatically. Also, I can prepare the script which you can just run on your computer once and it'll be working just like any other apps on your PC or laptop in the background but you'll be able to see the activity.
My bid is for the second solution and I can prepare it really quick. If you are interested in the server side solution let me know and I provide you with the additional information about how to do it because it'll be more expensive.
BTW, I don't need any milestones, you can pay after the script will be ready to use.
Best,
Sviat
