Today the webshop is based on Prestashop 1.2 and a bit poorly designed and the SEO-work has been crap.
2 options as I see it.
1) Update the current webshop to Prestashop 1.5.x.x and do the necessary redesigns
2) Create a new webshop basted on the latest prestashop version.
Always open for suggestions from you!
