EXHIBIT  31.1

                            CERTIFICATION PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I,  Jeffrey  R.  Hultman,  certify  that:

I  have  reviewed  this  quarterly  report  of Network Installation Corporation;

Based  on  my  knowledge, this report does not contain any untrue statement of a
material  fact or omit to state a material fact necessary to make the statements
made,  in  light of the circumstances under which such statements were made, not
misleading  with  respect  to  the  period  covered  by  this  report;

Based on my knowledge, the financial statements, and other financial information
included  in  this report, fairly present in all material respects the financial
condition,  results  of  operations  and cash flows of the registrant as of, and
for,  the  periods  presented  in  this  report;

The  registrant's  other  certifying  officer(s)  and  I  are  responsible  for
establishing  and  maintaining disclosure controls and procedures (as defined in
Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  for  the  registrant and have:

(a)  Designed such disclosure controls and procedures, or caused such disclosure
controls  and  procedures  to  be designed under our supervision, to ensure that
material  information  relating  to  the  registrant, including its consolidated
subsidiaries,  is made known to us by others within those entities, particularly
during  the  period  in  which  this  report  is  being  prepared;

(b)  Evaluated  the  effectiveness  of  the registrant's disclosure controls and
procedures  and presented in this report our conclusions about the effectiveness
of  the  disclosure controls and procedures, as of the end of the period covered
by  this  report  based  on  such  evaluation;  and

(c)  Disclosed  in  this  report any change in the registrant's internal control
over  financial  reporting  that  occurred  during  the registrant's most recent
fiscal  quarter (the registrant's fourth fiscal quarter in the case of an annual
report)  that  has  materially  affected,  or is reasonably likely to materially
affect,  the  registrant's  internal  control  over  financial  reporting;  and

The  registrant's other certifying officer(s) and I have disclosed, based on our
most  recent  evaluation  of  internal  control over financial reporting, to the
registrant's  auditors  and  the  audit  committee  of the registrant's board of
directors  (or  persons  performing  the  equivalent  functions):

(a)  All  significant  deficiencies  and  material  weaknesses  in the design or
operation  of  internal  control  over  financial reporting which are reasonably
likely  to  adversely  affect  the  registrant's  ability  to  record,  process,
summarize  and  report  financial  information;  and

(b)  Any  fraud,  whether  or  not  material,  that involves management or other
employees  who have a significant role in the registrant's internal control over
financial  reporting.
