I politely decline. Me assessing your gig is not going to magically bring you more sales. YOU need to take action to reach out to your customers. Gig assessments don’t bring orders. Successful, targeted marketing and promotion does. And you haven’t been doing that… so you don’t have any sales.
Start taking action to build your business, and you might find success. Merely creating a gig, and then sitting back and expecting everything to happen for you isn’t going to work. I am not going to help someone who isn’t interested in taking responsibility for their own gigs.
