Mise a Jours Magento

Bonjour,
Je vous contact car nous recherchons un/une développeur(euse) Web qui connaisse Magento
Voici l'url de notre site : [URL visible pour les membres Pro]
Nos principaux besoins par ordre d’importance sont :
-Mise à jour de sécurité: On doit passer à Magento 2.0 ou 1.9 (je pense que la 1.9 est préférable)
-Sécuriser l'admin du site contre les intrusions
-Modification visuel : Nous souhaiterions avoir un site un peu plus dans ce genre làpour 2016 : [URL visible pour les membres Pro]
