How to show the edit form of a page just below the page itself in the frontend?
You can output edit form of current node with node_page_edit function. So you can create a block programmatically(show this block only on node pages of your content type - Services for example) and output edit form with node_page_edit.

  if(arg(0) == 'node' &amp;&amp; is_numeric(arg(1)) {        
    $nid = arg(1);
    //you need to include node.pages
    module_load_include('inc', 'node', 'node.pages');

    $output = node_page_edit(node_load($nid));
    return $output;
  }


Here you can find an example how create block.
