You're an at-least-semi fat cat. You think you have some Buffett in you (Warren, not Jimmy). You want to be intimately involved in managing your money. You trust no one, like David Duchovny.
So you set up an Advisor Account. The advisor works directly with you, the client, to figure out where you're puttin' your dough. The cost? Well, if you get really nice Lakers tickets, you know you've over paid - but generally these are set up like wrap" accounts where you have a fixed percentage fee based on the assets you have under management with your Advisor.
