If your bounty campaign is paid by token with real value, You can ask for Hhampuz and Yahoo management service because they are expert on campaign management. But if you are planning to pay bounty hunters using token that no assured value after the campaign is over then don't expect that reputable campaign member here will accept your offer unless your project is backed by VC or you have enough funds to cover sufficient marketing expenses.
There are tons of bounty campaign on the altcoin section that disappear after distrubiting worthless token and wasting participants time and effort. I hope that your project is not same with them.
Appreciate your response. Can absolutely appreciate that, but as mentioned in the OP, our project has been operating since 2018 and only now have we decided to launch our own token. Our project is not at ICO or anything similar, the token will have value from day 1 and will be available to be staked, swapped, held and spent.
In this case they might accept you offer. Take note that most of campaign manager here requires escrow to secure the bounty campaign funds. It's either you will sent the tokens to them or hire a separate trusted escrow for the funds. I hope that you choose the right bounty manager. There is still a lot of underrated bounty campaign manager in the forum maybe you should consider them. But the name that I mention above is the most solid campaign manager in the forum. They are currently managing multiple campaign that's why I recommend you to try hiring underrated campaign. But if they accept your offer then that will awesome.
