There are a few boutique real estate offices in the area that say they do this sort of thing.

I work with a private boutique lender & investor.

Only caveat to that, is that there are a few boutique buildings in Waikiki that rarely have units listed on the market so it can be challenging to get recent financial data.  

@Scott Lester Are you asking if there are boutique multifamily brokerages out there?

Either keep it simple with low fees with wealthfront.com, or, if you want a boutique investment firm, check out what Jerry Verseput at veripax.net has to offer.

They know about things before the market and as of today I have the inside track as the commercial and business broker on a major distillery, iconic local restaurant, boutique hotel and real estate owners that are open to join venture development.

My wife wants to retire to a boutique hotel on a Greek island, maybe 20-25 guests.

Think indy coffee shops, boutique stores, trendy, etc.

Already talked to counselor "boutique" co. that works with people just like me (weeks of searching paid off - these guys don't advertise very well).

Brookside: Located south of the Country Club Plaza, Brookside is a popular neighborhood with a mix of historic homes, trendy restaurants, and boutique shops.
