How to save a found Vanda?

[makromolekula]

Today i was strolling around with my boyfriend and I found two Vandas by the bin. Somebody left them there maybe hoping somebody would find them.
Without thinking I took them home and now I am trying to breath and focus because I dont know what to do with them.
I have 10 phals which are doing great but I know it is nothing to be very proud of because they grow relatively easy.
Thing is I didnt even know what type of orchids they were untill I googled it up.
It is very very cold in Slovakia and I dont know how long were they left there. They seem to have good and huge root system and many "levels" of leaves.
Please can you help me what to do with them now, I think I need to act very quickly if i want to save them. according to my research it seems they are hard to grow so I would pass them to somebody more experienced but now I want to make sure for I did everything i could to save them.
Thanks a lot, you are my angels.
