I've done this a couple of times now in order to get some orders flowing into my gigs right off the bat, it's really simple. All you need to do is find another gig in the same niche as you, for example article writing. Next, look for the people that have left a negative review. Generally these people are still looking for the work to be done because that never happened when they ordered the other gig. This is where you come swooping in with your own gig saying something like "If you weren't happy with the previous gig you ordered, you should buy mine, I'll get the job done properly" Unfortunately only the people who have gigs up themselves seem to be contactable, though I'm usually still able to contact at least a handful to get things rolling. But be careful doing this, it's a bit of a fine double edge sword. These people have been messed around before ordering something similar to what you're offering, so they might come into it a little hesitant or agitated. Just do a good job and chances are you'll end up with a returning customer.
