Most of the bounty managers have their website in which they upload the bounties in which they manage and make it easy for the hunters to find the bounties they manage and easy accessible for hunters. But these managers don't do upload spreadsheet for hunters to see their stakes.
The bounty managers on Bitcointalk always have their spreadsheet shown to hunters and make them awear of the qualified people and the rejected hunters , but to find the bounty of some favourite bounty managers is not that easy.
Does that even matter at all? You should only be worried about finding a very good project, one that is paying and not a scam that is going to waste all your time and cause you to do heavy and after all the work you wouldn't get paid for it. So where ever you're doing the project doesn't matter, you just need to find a project that is good. So no matter the project you find, you should just try to do more research about it and know whether they are reliable or not and what you're likely to gain from doing it. Doing bounty is not really an easy job to do.
