Add to card button at the bottom of a product page

-- url of the page with the problem -- :http://tinyurl.com/pna3g2l
-- HikaShop version -- :2.2.2
-- Joomla version -- : 2.5.16
-- PHP version -- : 5.3
-- Browser(s) name and version -- : firefox 26

I would like to have an introduction of a product and show only the add-to-cart button at the bottom of the page. Preferably without the image and the quantity box

Can anyone tell me which files I need to adjust and what exactly needs to be adjusted (with my very little knowledge of PHP)

Thanks in advance!
