If a team can run the project the way they want and they can maximized their medium of advertisement and they can do what ever they need to do to have a smooth running ICO project they dont need any ICO advisor, as you can observe there were lots of ICO team that has an advisor and in the end the project went successfully and some were not but still they dont pay people, for me advisors are just and introductory that they need to gain the attention of the investors. Sometimes a good bounty manager can be an advisors for the ICO.
