Automating a process on website & deep knowledge of cloudflare waiting Queue

A website has appointment slots. The slots are very limited in number and it can open anytime 24/7 . since the timing is not fixed, manual checking always is not possible. We require an automated system that always keep checking the slots and once the slots open it should book automatically.
There is also cloudflare waiting queue set up as soon as slots are open. You should also have knowledge of the waiting lane queue system and make your scripting considering this queue system.

Note-This is a long term project. If you can do this work effectively, you can be hired permanently with monthly payouts
