hmmm... as designers its very hard to thinck a tag lines... What is the first thing that came in your mind when u imagine ur company name?

MVP stands for "Most Valuable Player" in the sports world.  The MVP get''s the award or recognition at the end of the game or series for his or her contribution to the success of the team and/or the win.    Perhaps some type of play on words that get''s that across and that we can be their financial MVP that saves them money, taxes, etc.    

Perhaps something like, " You play the game, let us we game-plan your success "  Or maybe, " Your Financial Success is Our Game".  I am not in love with either of those, but perhaps something similar.
