     Response
     --------

     We have  revised our  disclosure  to  indicate  that on July 11,  2005,  we
     determined  that there were errors in our  accounting  for the valuation of
     equity consulting service  transactions  during the quarter ended March 31,
     2005 and that authorized officers discussed the matter with our independent
     registered public accounting firm.

     The  Company  acknowledges  that:  1) the  Company is  responsible  for the
adequacy  and accuracy of the  disclosure  in the filing;  2) staff  comments or
changes to  disclosure  in  response  to staff  comments  do not  foreclose  the
Commission from taking any action with respect to the filing; and 3) the Company
may not assert staff  comments as a defense in any  proceeding  initiated by the
Commission or any person under the federal securities laws of the United States.

     We trust that the  foregoing  appropriately  addresses the issues raised by
your recent  Letter of Comment.  Thank you in advance for your prompt review and
assistance.

                                Very truly yours,

                              /s/ PETER BROCKLESBY
