I typically don’t ask for a quote upfront since they are very fair with their business and billing practices.

I could definitely see a large law firm (Orrick, Venable, Cooley, Fenwick) doing what you describe. I’ve worked with 2 firms just listed, and their billing practices were ridiculous.

I’ve had a lot more success (quality and price) working with boutique law firms, where your point of contact is always a partner instead of your account permanently being pawned off to an associate.

Email is in profile if you want an intro to the law firm I use. Great boutique firm based in Bay Area and extremely good price/quality/value.
