[Linked object blinking script needed]

Should I just start this topic there and how much is a fair estimate on pricing that? I honestly haven't a clue and rather not have people get vicious or critical

[Linked object blinking script needed]

I made a mesh head for something for the first time but need a really specific kind of script. I'm pretty basic in scripting and can only really learn from existing snippets but cant seem to find something that really DOES this. What I have is a head with the eyelids in 4 states (kinda like kemono eyes- which script doesn't work from) 0 being open, 2 frames of mid blink, and 3 being the closed position. What I need is a script that toggles the alpha between only those linked eyelid objects in a sequence and a timer that makes it do the sequence every 3-4 seconds. Id greatly appreciate it if someone could whip up an example, I already tried buying a script from market place that.... didn't work out very well. If it relies on the linked name or description for the sequence do tell, and much love
