Prestashop theme/module installer and backup maintainer

Need someone to install themes and mods on Prestashop and make it back up daily. I have one theme i want installed and modules to install as needed. I would like an auto back up that is 2x a day and can easily be restored. This is an ongoing project where if i need you after initial setup, i will txt u for updates. It is for one site now but if i can stop it from messing up, i will add additional sites. This is a by the hour project and i need someone dependable with a good work ethic.
