If I understand you correctly, you can just create the fields that you want to search on, and then add a form to your page. The following form example would be to search two fields called "Hosting Type" and "Cost".
<form method="GET" action="
http://www.yourdomain.com/links/search.cgi">
<p>State<br>
<select size="1" name="Hosting Type">
<option value="Select Value">Select Value</option>
<option value="PHP">PHP</option>
</select><br>
<br>
Cost<br>
<select size="1" name="Cost">
<option value="Select Value">Select Value</option>
<option value="
Less than $20">Less than $20</option>
</select><br>
<br>
<input type="submit" value="Submit"> </p>
</form>
