Hi all,
I still don't know if I will join the project, but here are a few info:
Soph coccinea is know to require cool to very cool temperatures in order to bloom... Otherwise, in intermediate temps it grows very nicely (i know it very well !) into a big ball of leaves... never blooming.
Also the ones at New World orchids are Japanese selections of Soph coccinea (usually 4N clones, with bigger and rounder flowers) which tend to be way more expensive than regular 2N coccinea
I don't know if it was ever in a project or not, but rupicolous Laelia (not called Cattleya) are great little (to miniature) plants, not too demanding aside from light, and quite easy to find on both sides of the atlantic...
In Canada, we have a vendor not mentioned yet who has good quality plants (as well as not so good), it is
Orchids at Hawaiian Botanicals
And lastly, if the choice goes towards a Paph or a Phal species,
ForestView Gardens is an excellent choice
