The 2'' BL is not a super hard install, but it is time consuming. My 3'' BL took an entire weekend. However the 2'' is much less involved. Would probably take a couple people the entire day to do it. Main thing is you need a couple good floor jacks, and a whole bunch of 4x4s to put under the body.

I am also willing to give a hand with any work that needs to be done that day.
