150g FOWLR Cost????

Hi everyone. I am new to saltwater aquariums and I am interested in starting a 150 gallon FOWLR tank. I was just wondering if I could get some advice as to the approximate cost of this kind of tank, not including the tank and stand themselves. I would just like to know the cost of the equipment, set up, maintenance, livestock, etc. I understand that this is an expensive hobby, so I would just like to get an idea of the cost I am in for before I begin. I would appreciate your help. Thanks.
