Here's what my friend suggests to do in order to succeed with this business project:
1) Limit the number of sales per image. The goal is to make these illustrations available for a limited number of people to avoid the same stuff published everywhere. Let's say I only sell 100 copies of a specific illustration and delete it forever (does it really make sense?)
2) Don't charge on per download basis at all, only sell illustration packages as high ticket products (to me, it's a really bad idea)
3) Connect with high ticket buyers using social media sites like Twitter and LinkedIn, don't waste your time and money for paid advertising, especially at the very beginning, because it doesn't guarantee you customers with sufficient funds for expensive illustration packs. People usually search for cheap stuff in this niche (who knows)
Do you agree with these recommendations? Selling illustration packs as high ticket products sounds too good to be true. I believe most income would come from customers paying per download and I should not offer limited editions. What would be the real requirements to achieve high ticket sales with digital art?
