Orchid in vivarium?

[FwoGiZ]

I am a total noob regarding orchid and even plants in general... I know a lot bout vivariums but the only thing I lack is plant knowledge!
So I am coming here because I am looking for some viv friendly orchid and orchid jewels!
I will be ordering from this websites
I am looking to buy one orchid jewel and one orchid. I need a small plant that will do good in 70-85F, 70-90% humidity.
Also, I am looking for orchid around 14-19$ since I am new and might very well kill it ;p
I had my eyes on Isochillus linearis and Dendrobium seidelianum.

I can mount them on driftwood in the viv, or plant them in the soil or in a coco fiber basket for extra drainage.

Tx in advance!
