What orchids to choose?

[Zdenglan]

Hi everyone!

I am a proffesional gardener in the NW UK and I have been presented with an opportunity to grow a couple of orchids to be displayed in our garden tearoom when in bloom. We have a 2 compartment heated glasshouse with winter minimum temps being 5C and 10C. I am looking for a max. of 10 relatively easy and compact orchids that I could grow in these conditions and possibly achieve perpetual flower display from march to september.
Those that I know I should be able to grow are:
Couple of Pleione species and hybrids
Coelogyne cristata
Coelogyne intermedia
Coelogyne ochracea

Please can you advise on other cool/very cool growers that are from your experience reasonably easy and reliable? Winter rest is a bonus - that means less work for me.. Scent is important to me too..
Thanks ever so much for your ideas!
Happy growing!
