Download & upload a page onto your site

We have a competitor who has written some extremely self-incriminating remarks on a bulletin board page, but it appears that he has forgotten he ever said these things. We would like to point people to his remarks (through a link from our website), but as soon as he discovers this he will simply edit his remarks or just remove them entirely. Of course we could archive the bulletin board page and post it on our own website, but our copy would not be credible, since we are biased and, hypothetically, we could have manipulated his words. Therefore, we are looking for someone to do the following: (1) archive the bulletin board page on your computer, (2) upload it to your website for us to link to indefinitely, and (3) add a statement that you are an unbiased, paid professional with no interest in this matter between us and our competitor, that we have never met 'til now, etc. Should be a simple matter of downloading a page and then uploading to your website for public access. (No internal link required on your website, you just give us the page's URL.)
