Hello, I want a web push notifications system on my small 4 pages html and css site that I haven't published live. So basically, I want to subscribe users to receive my promotional push notifications. So, the way I want them to subscribe is that, when a visitor visits the sites or any page of the site, he or she is asked to click Allow and if visitor clicks don't allow, he gets redirected to the same page until he or she subscribes to receive my notifications. I DON'T WANT TO USE third party tools like firebase or onesignal and in the admin panel, I want to send have the option of sending notifications to specific number of subscribers or all of them at once, I want to choose their country location or all locations, I want to choose browser type or all. I also want to be able to resend the same notifications to subscribers who didn't click on the notifications and also to all newly subscribed users. I will be sending promotional push notifications of anything I want. The notifications should have the title, logo and the image but with a link that redirects user once he or she clicks on the notification message. I also want to know how many subscribers I have and how many from a specific country. My budget for this is $100, can you work on it?
