Okay, so that is equivalent to 1 person working 40 hour weeks for 7 weeks. So, one person pulling $6K a day. ($1.5M/yr) I think you could find legal support for less than that.
Assuming they could maintain that for a full year, $6K a day is only 2.2MM. Also keep in mind that these hotshots don't do much of the grunt work, they offload it to any number of junior associates (which that hourly rate has to cover, in addition to other business overhead). Still not a bad gig if you can get it.
