When I visit the link you provided the page loads at the top and then once the iframe loads I am taken to the bottom of the page. So I understand what you are asking.
However, there are several errors on this page.

You may wish to correct those and if the issue persists post back and I will take a look then.
You could also try <iframe style="position: absolute; top: -9999em; visibility: hidden;" onload="this.style.position='static'; this.style.visibility='visible';" href="..."></iframe>
Which will hide the iframe then bring it back once the page is loaded.
