Getting nails done

So I’m wanting to get my nails done tomorrow, and actually keep them maintained. I’m wanting something like the pic below-hopefully shorter though-is that an option?!

Would this be considered acrylics?

What type of set should I ask for that is somewhat low maintenance? How frequent would I need to get a fill or a new set? I’m anticipating going back every 3ish weeks, does that seem reasonable? I’ve had nails in the past but usually just for big events, I didn’t maintain them for any amount of time because I wasn’t sure how honestly, and I would like to this time around.
