Are there any jobs for Esperantists?
Some has to setup the meetings and teach it right?
There are a few "full time Esperantists" in the world.
In the US, there is one full time staff member at Esperanto-USA. (At least, I think it's still full time -- 20 years ago it was two full-time positions.) The situation is presumably similar in other places around the world. There are also full-time volunteer positions available which pay only room and board.
Evildea occasionally posts here on Duolingo that he makes money from making videos in Esperanto. I suspect he does OK, but I have not heard whether he's been able to quit his day job yet.
I knew a person (she's actually fairly well-known, as you'll see) who spent a year traveling Europe using Esperanto. She then tried to leverage that into a gig traveling around the US giving public talks about her experience. I know she managed to give a few talks, but it did not become a full-time paying gig for her as far as I know.
I've been paid for Esperanto at least twice. Most recently I was paid by a local theater company for language consulting services related to Esperanto. I have also had someone offer to fly me from NY to TX to help rally for the name change from ELNA to Esperanto-USA. I've also received various free books and music CD's in exchange for writing reviews or dubbing voices. I'm pretty sure I made money for my work on the movie "Flying an Octopus", and a T-shirt run that I did 10 years ago probably broke even.
I would expect that most teachers of local classes are not paid. I see a few people on iTalki trying to charge for Esperanto lessons. I have no idea how much business they get. Frankly, I hope it's not that much - with FEC and Ekparolu (and others) offering lessons for free. I'm pretty sure that some of the staff at NASK receives a small honorarium and possibly transportation. Certainly not enough to live on or to make up for lost wages while they're away.
I'm pretty sure that the folks who work at events like the Universala Kongreso are only paid in the sense that they don't have to pay the kotizo (registration fee).
Recently Appen was posting for developers with Esperanto language skills - presumably for temporary or part time work.
For sure, though, there are plenty of stories of people who have found work through Esperanto contacts.
The italki lessons do not give much business, you are right. Most of the Esperanto teachers there teach Esperanto along with their native language. I've had an interesting italki experience of teaching Russian through Esperanto, but that's also a very rare thing.
Since posting the above... 10 months ago... I've been encouraged to become a teacher on italki and it's working out pretty well for me.
Edit: since posting this update six months ago, I have done a bit more as a "professional Esperantist" - but ultimately the "day job" was calling me.
Like Salivanto I had a run of shirts which were purchased and sold by Esperanto-USA some years ago. I still make a trickle of money from my designs on CafePress. I recieve a complimentary DVD from my work on the Mihm movies.
A few years ago I was paid a small chunk of money to translate a few paragraphs of a book by William Shatner into Esperanto (Shatner Rules.) I also had to include a pronunciation guide for the audio book. From what I understand his pronunciation still wasn't so good. I'm not getting rich here, but getting tips for having fun is nice.
Chinese Radio International employs at least six full time Esperanto speakers from memory. The General Director of UEA is a fulltime employee. I make a part time wage off Esperanto which accounts for about 30% of my overall income (This comes from three separate sources).
If you want to make money through Esperanto, you need to make the opportunities for yourself. There are very few salaried positions. However, the community is growing at the moment so I suspect this will change in the next five years.
Besides from what Salivanto has already mentioned, the Universal Esperanto Asocio employs 7-9 people, (not all full time) in their office in Rotterdam. And probably a few people are employed at China Radio International.
I have been trying to find a way to make a living through Esperanto for a decade (Translating, conference interpretation, bloging, publishing and so on). I have realized that it is much more clever to use your new ability to meet people through Esperanto to make a living in a business which requieres you to meet people. I explain it here in video http://libreparlemlm.com/sufichas/
