There are a lot of reputable bounty managers on this forum and I think they can take the job of managing PR / media activities.
I can recommend a few names:
BountyDetective
DarkStar_
Hhampuz

OP is looking for PR/communications staff, or perhaps manager. I'm not sure the names you mentioned do such thing. A bounty manager is not the same with a PR/communications manager.
OP, I suggest you move this topic to the
services section as you are looking for someone to do certain services for you.
And it would definitely help a lot if you give even a brief overview of your ICO or project.
