Wow, that’s really sad.  The big three are Bank of America, Morgan Stanley/Smith Barney, and Wells Fargo. 

  I can't imagine you're going to have "little to no resistance opening accounts" at one of those firms.  Especially in light of the last 6 months.    My suggestion, go indy.  Find an indy rep in your area that would let you set up shop with them.  Rather than try to move your existing clients into a company who's probably got a black eye, just tell them you're hanging out your own shingle.  I would think in this environment, you'd have a lot less resistance in indyworld than you would at one of the beaten up big three.
