Another vote for Fidelity. I've always found their phone advice clear, simple, understandable, not pushy. I chose Fidelity over Vanguard for this. Fidelity customer service is slightly better than Vanguard, 24/7 phone instead of 9-5 for example.
An example of Fidelity customer service: In Dad's final year we simply instructed Fidelity to gather up all his random various accounts and stock certificates from elsewhere. They sucked everything up from all over the place without additional input from us. Next month everything was on his monthly Fidelity statement. Excellent service! I've pulled IRA's into my Fidelity account similarly, just one phone call and the transfer-in goes. They know how to deal with all the other financial entities.
I've never looked at Schwab but it's my impression you would encounter more of a sales pitch there.
