What do you mean by "lined up" the two clients? I mean, do these people expect you to start working for them (because you made them believe that somehow)? If this is the case, I don't see how you can tell them "Hmmm, sorry, I changed my mind, I am not going to leave my current employment anymore." and get away with it. Still supposing that the two clients (wishing to give you combined 150K per year) are in the industry, most probably in an executive role. On the other hand, putting for a moment aside the actual amount of money your current employer offered you, it is a 50% raise, it may happen that they somehow undervalued by accident your contributions, but 50% seems a bit too much to be an oversight. Such a huge difference would undermine the (IMHO needed) fiduciary relationship with them.
