Help identifying and care tips

[karebear1996]

Hello, I received this beautiful orchid at an auction and have absolutely no clue what it is or how to care for it!

The plant stands about 3.5 ft tall from end to pot. it has one main stem with two off shoots and 7 very large, thick, green leaves at the base.
I've attached a few photos to help identify the orchid.

If anyone can give me any advice on how to care for it I would be very grateful.

- If I knew what kind of plant it is I could read on care instructions
-Watering, trimming, feeding
-Is it ok in its current pot?

and on and on lol. I have a black thumb and I'm worried I'm going to hurt it so again if any of you have advice I'm all ears!!

Thanks in advance
