One persons 'good' architect may well be someone elses nightmare, so try to talk to as many as you can, chech out their built work if possible, and ask for references.
My advice would be to shop around and not to limit yourself to Architects in your immediate vicinity. You may be surprised as to how far Architects are willing to currently travel.
