         Re:      Registration Statement on Form S-8

Gentlemen:

         We refer to the Registration Statement (the "Registration Statement")
on Form S-8 filed today by kforce.com, Inc. (the "Company") with the Securities
and Exchange Commission, for the purpose of registering under the Securities Act
of 1933 an aggregate of 3,000,000 additional shares (the "Shares") of the
authorized common stock, par value $.01 per share, of the Company being offered
to certain employees of the Company pursuant to the Company's Stock Incentive
Plan (the "Plan").

         In connection with the foregoing registration, we have acted as counsel
for the Company and have examined originals, or copies certified to our
satisfaction, of such corporate records of the Company, certificates of public
officials, and representatives of the Company, and other documents as we deemed
necessary to deliver the opinion expressed below.

         Based upon the foregoing, and having regard for legal considerations
that we deem relevant, it is our opinion that the Shares will be, when and if
issued in accordance with the exercise of options granted under the Plan, duly
authorized, validly issued, and fully paid and non-assessable.

         We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement.

                                      Very truly yours,

                                      HOLLAND & KNIGHT LLP
