I'm getting a few orders a day, the trick now is, because fiverr are opening sites in other countries (just started fiverr[dot]de, and fivver uk is coming soon I beleive) you can start to scale up ( as long as language barrier isnt a problem)
the fiverr clones get no traffic as far as I can tell, I'm on a few with no orders in 3 weeks.
Oh and of course, when the work is completed, whatever it is, dont forget to add a file with your email address on it for repeat business (offer bulk discounts etc) thats where the money is. Fiverr is just a method of generating leads
