To be very frank, nobody will hire an inexperienced person as their bounty manager. So to establish your name in this industry, try to manage first 2 campaigns for almost free . After that start asking payment in their tokens. When you have the list of atleast 5 or 6 successful bounty campaigns in your portfolio, start asking for btc or eth.
No way am I working for free for a couple of projects, fuck that. I agree that people might be rather hesitant to pay somebody inexperienced, but my bet is on a couple of things I will showcase in my service announcement thread. I already have a template bounty thread, a template spreadsheet and a really well-defined set of rules.
While I was researching how other bounty managers started their service, I found absolutely horrible services, with shitty designs and bad English, getting 2-3 projects in the matter of days after their entrance on the market. If those people could do it, I will easily outperform them.
I have yet to kick off my service, just polishing the last rough edges. It's been 3 interesting weeks, I'm dying to see what's ahead.
