Κατασκευή ενός Online Καταστήματος

I am junior software developer and have undertook to complete, bring live and administrate a website for my best friend (i am doing it for free and in order to learn magento). My friend had some problems with the person that created this website so this person stopped working and supporting so i took the responsibility to bring it live and learn to administrate. I have no experience with php nor with magento but i have designed small website projects(for learning purposes) with python (googleappengine and django) and java(spring). What i wanted to ask you if you can support me finsh this website and guide me until i am able to run it by myself. As this is now is a real store and not a project for learning i wanted to have a backup when i am lost or when i need to implement something completely new for me. Ideally i was thinking if it is possible to teach me and show me what needs to be done and review and give feedback when i have done it or in some occasions when you have done it. Thank you for your time, Best Regards Andreas Kyritsis
