I know this may sound completely off the track, weird and nonsensical, but...
Can you apply the principle of Inverse Economy to your promising app? Inverse Economy basically states that workers pay to work, since job titles are a commodity.
In simple words, your app could empower not (just) skilled professionals to sell their work, but rather talented idealists to buy work. So, instead of Joe offering Jane to work for him for X $/hr, Jane would offer service to Joe for Y $/hr. Imagine the "inverse" Steemlinked as a place were great ideas are rewarded, and not (necessarily) top work.
You could have, also, just a portion of the site dedicated to this "inverse" experiment.
Hope it helps!
