Most important thing that your gig requires

[Guest sandramooni]

According to me, the most and foremost thing that your gig requires is uniqueness.
A unique gig will fetch you more order.

That will get you through a few orders until your gig ranks better and other sellers take note of that and replicate it creating more competition and less orders for you. Yes, it is one of the factors for success, but a very small one.
