Here are a couple vanilla projects located in Costa Rica.
I talked to someone at Vanilla Export Company months ago, but lost contact.
SODG is a Dutch investment group that is betting on teak plantations and vanilla in Costa Rica. Google says they were sued and might not be active anymore…
After some reflection, I added Costa Rica to the list of vanilla producing countries because beans seem to be available from Rainforest Spices. I've written for further info, I'll keep you updated with any replies.
