I just put up two gigs on Fiverr (see below) and so far, so good.
The vibe is like how GenLighten operated five years ago before it changed to a subscription model and shut down. There you were able to put up an offering for all to view and buy. At Fiverr you do the same in a comparable way.
The experience at Fiverr is much better, though, as you can see more stats about how well your offers are being received. You can also create links for marketing, which you could not easily do at GenLighten.
Right now, the competition in the Genealogy category seems all right. Most entries in the genealogy / family history section are good, and some not so much. I can’t comment on the quality of the deliverables, though, since I’m a seller, not a buyer.
I am thinking about adding a third gig, for proofreading, editing, and writing family histories.
