I think you have misunderstood what Custom Post Types are used for, if your trying to gather data try a plugin called Contact-Form-7 or if you want to post data then try using custom fields with the name of Contact Person, Address, Telephone, Cellphone, Fax, Email, Website.
You can echo custom fields into your theme files with the following code:
<?php $custom_field = get_post_meta($post->ID, 'custom-field-name', $single = true); ?>
<?php echo $custom_field ?>
if you add a custom field called: ‘contact-name’
then you can setup the code to echo the data as follows;
<?php $contact_name = get_post_meta($post->ID, 'contact-name', $single = true); ?>
<?php echo $contact_name ?>
