Hello,

I don't really fully understand what you mean.
If you mean who can advise you when you're thinking of trying to build your own Initial Coin Offering, then I dare suggest you don't work in that direction at all.
In order to issue a coin offering with any embedded value and any hope of really serving those who decide to purchase the tokens you give them for their ETH or BTC, then you already have to have a really good idea, and just as much, you need to have an exceptionally talented tech team on board.

Without these there's no way forward.
The tech team is just as difficult to put together as the business team promising to achieve the results set forth in the white paper.
At PROSUME.io we didn't need any advisory. We had it in house.
I think ICO advisory could even be an interesting business but it doesn't really exist today.

If I haven't answered your question please feel free to contact me
All the best
