Findeo demo uses  Contact form 7 plugin for contact form, and it’s recommended one. After installing this pugin go to Contact → Add new (or edit current one) and in Form field paste what’s below:

<div><label>Name</label>[text* your-name] </div>
<div><label>Email<span>*</span></label>[email* your-email] </div>
<div><label>Message<span>*</span>:</label>[textarea your-message] </div>

[submit "Send"]
<div class="clear"></div>

Than at the top of page you’ll see shortcode, for example  (it will have different ID on your website):

[contact-form-7 id="123" title="Contact form 1"]

Use it on a page you want to have contact form.
