Dear Mr. Mulholland:

      We have reviewed the above referenced filing and have the
following comments.  We have limited our review to only your
financial statements and related disclosures and will make no
further
review of your documents.  As such, all persons who are
responsible
for the adequacy and accuracy of the disclosure are urged to be
certain that they have included all information required pursuant
to
the Securities Exchange Act of 1934.  Please address the following
comments in future filings.  If you disagree, we will consider
your
explanation as to why our comment is inapplicable or a future
revision is unnecessary.  Please be as detailed as necessary in
your
explanation.  In some of our comments, we may ask you to provide
us
with supplemental information so we may better understand your
disclosure.  After reviewing this information, we may or may not
raise additional comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or on any other
aspect
of our review.  Feel free to call us at the telephone numbers
listed
at the end of this letter.

4. Tell us why your "net" presentation  of PEO service fees
appears
to exclude payroll taxes and benefits related to PEO staff.

your

	We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filings reviewed by the staff to
be
certain that they have provided all information investors require
for
an informed decision.  Since the company and its management are in
possession of all facts relating to a company`s disclosure, they
are
responsible for the accuracy and adequacy of the disclosures they
have made.

	In connection with responding to our comments, please
provide,
in writing, a statement from the company acknowledging that

* the company is responsible for the adequacy and accuracy of the
disclosure in the filings;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with
respect to the filings; and

* 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.

      In addition, please be advised that the Division of
Enforcement
