Create a custom Drupal webform template

Hi, For a customer I'm creating a drupal website. This website contains a multi page form which is generated by the WebForm Module. The problem is that this form is heavenly designed en nowhere near the default output of this WebForm module. So I have to create a custom template for it. That's the part where I get stuck. I can provide a export of this form (with node export) and a file with the html form. So I need somebody to provide me a template. Regards Norman
