A custom block on the top of the form ?
Or edit contact form tpl. I do not use Contact 1.7, so I can't tell you more.
But if you use xForms (old name : Liaise), you could easily transform it.
Example :
xforms_form.html
<{if $form_is_hidden != ""}><p><b><{$form_is_hidden}>b>p><{/if}>
<{$form_output.javascript}>
<h1><{$form_output.title}>h1>
<{if $form_intro != ""}><p><{$form_intro}>p><{/if}>
<form name="<{$form_output.name}>" id="<{$form_output.name}>" action="<{$form_output.action}>" method="<{$form_output.method}>" class="xforms" <{$form_output.extra}>>
<table class="pad20">
<{foreach item=element from=$form_output.elements}>
<{if $element.hidden != true}>
<tr>
<{if $element.body == "" }>
<td colspan="2" class="top bold">
<div class="caption-alone"><{$element.caption}>div>
td>
<{else}>
<td class="top bold" style="padding-left: 25px; width: 200px;"><{$element.caption}>td>
<td><{$element.body}>td>
<{/if}>
tr>
<{/if}>
<{/foreach}>
table>
<{foreach item=element from=$form_output.elements}>
<{if $element.hidden == true}>
<{$element.body}>
<{/if}>
<{/foreach}>
form>
Main tip is : <{if $element.body == "" }> ...
Good luck
