Oracle Database Administration Lessons

I need some lessons in Oracle Database Administration. Basically to cover various topics, and we can make a course plan for the online lessons. The lessons can by via skype or any other suggested method. I have experience in SQL and Oracle programing... but I need to focus on DBA (Dtabase Administration) Basically the topics to cover are: - Complete installation process of Database (in various types of servers) - Database Configuration - How to turn on and off Services - Backup and restore options and how to implement and verify backups - Database Optimizacion and Tuning how many hours do you think this will take so we can budget the project ? Thank you
