Hi. The project is complete. Right now I'm recording a video where I show this software in action. I'll post a private message with a video in a few moments.
If you want this software, just hire me and I'll give it to you right away. Of course, any adjustments will be done if needed. For example, right now it checks it every 3 seconds, but I it can be adjusted to any interval you want. It's aware of houses that were already clicked so it ignores it. It keeps track of houses that it has clicked in a file, so even if you close the software and start again, it won't click those houses again. It uses a chrome browser for checking and a firefox browser for clicking as you've suggested. I looked at the site and it requires login, so it will ask you to login with firefox when the software starts, then you press any key and it's completely automatic. It runs on windows.
