Gigs by Darren Nevares
You get to be on a podcast as a guest via Skype. Then you can say whatever and talk about anything. It will be only 0.50BTC per a show. Check some of the podcasts here http://kageegee.bandcamp.com/album/screwing-that-bassline-a-podcast-2. This could be used as advertisement, show off a talent, or just simply talking and goofing around.
