You provide a blue collar approach to a white collar circumstance. Your building states your business is professional tax handlers/accountants housed in an inviting and secure building.  Every approach or method Todd advised me to use was explained in terms that I understood.  Once people understand how complex the process is, they will realize how a professional is the only option for them.
