Smart garage door opener- on the cheap

I am automating what I can to make things easier due to my disability. It also needs to be as cheap as possible and rental friendly.

My garage door is Steel-line, if that helps. (Australia)

I want to use it with contact sensors so it won’t open if the normal garage door is open (and let the dogs out), automatically close if I drive away and have forgotten about it, and close at night if it has been left open.

My IT skills have reduced, and I am using Alexa.
