What Level of Services and Fees Should I Expect from an Estate Attorney

My question involves estate proceedings in the state of: California.

My mother passed recently. I am named executor and trustee for her will and trust.
She has a pour-over will. She doesn't have much in the way of assets, but her trust does have a paid-off house titled to the trust.

I'm looking for an attorney to help me with those duties and I'd like to know what range of services I could expect from him or her. Or is there even a range of services?

I don't know if I should expect just a one hour consultation, prepare my questions as comprehensively as I can, take copious notes, and then off I go trying to do everything myself properly on my own; only returning for another hour of consultation if I think of new questions. Kind of like a pay-as-you go engagement.

Or do I explain what I need done, and the attorney quotes me a fixed fee, takes it from there, handling all forms, court visits & filings, notifications, etc, and provide me progress updates along the way and assigns me action items for things I need to do.

Or is it something in between those two extremes?

Also, any ball-park estimates on what I can expect to pay in fees would be appreciated.
