I have a niche mobile app published in the app store that's well received by my target audience. However, I've yet to be able to get my sales to outweigh my advertising expenses. I'm thinking that perhaps I need to find some sort of person that can help me get the word out (whether it's calling people, social media, or traditional advertising). What kind of person am I actually looking for? And where would I find them? It would be ideal if they'd be interested in profit-sharing, though I don't know how realistic that is.
Thank you for any insights you have to offer!
