I see some of the people on this list have been ICO advisors on several projects
https://icobench.com/experts. I don't want to recommend any of them, but you can look at their portfolios especially those who have been involved in projects similar to yours.
Keep in mind that success will return to the potential and prospects of your own project.
Good luck.
Edit: Check this out!
https://bitcointalk.org/index.php?topic=5184050Icobench is one of the best place where project owners can find some advisors unto their projects but I will also add
www.linkedin.com where OP can also find some blockchain experts and other more. Mostly those high profile guys always stay there so its good to post this there since for sure he can get quality guys there.
