How to use Promoted GIG Offer?

[shafkat_ppc]

I am having a little bit less order than previously after editing my GIG. So I am thinking about taking the promoted GIG offer. But I am little bit anxious about whether I go for it and if I haven't any order than my money will go to waste. So what is the best cpc to get the order and what are the best practices of using promoted gig offer? Please share you valuable experience.
