You I understand your problem is that after post back page is loaded again and of course scroll-bars are set to top again. You would need to mark form with <a name="contact_form_anchor" id="contact_form_anchor" ></a>
then you could add this script :
<script>
jQuery('<a href="#contact_form_anchor" style="display:none;" ></a>').appendTo(jQuery("BODY")).click();
</script>
to scroll page to that place automatic-lay on page load. You could add both thing is php file containing form code.
That's all we could help you with other people components. If you would like we do customization you can pay us.
