The top photo is an Ascocentrum miniatum which I consider to be blooming size, even though it hasn't bloomed yet. It's a pretty bullet-proof species and handles wet and dry, cool and hot, but I think it wants more light than I can provide. The part you see is ~7" from wingtip to wingtip and, although hidden by the Spanish moss, there are new growths at its base. It'll get nice bunches of small orange flowers.
The bottom photo is a Dendrobium aphyllum, also known as Dend. pierardii. It's one of the deciduous species that sheds all its leaves every year and then grows lots of very nice pink & yellow blooms on its bare canes. Then it starts a new growth cycle, which you can see is underway now. One great thing about it is that it needs essentially no attention through the winter because it spends months as a pot of sticks until starting to blooming. The longest cane is ~12" and it's been a regular bloomer for 4+ years. Notice that the canes curve down below horizontal, so they're often hung in a sideways pot or in a coconut husk or whatever.
You can find examples of the flowers of both at http://www.orchidspecies.com/. Let the bidding for this pair begin at $10 and I'll pay for shipping if they bring more than $18.
