Interested in How-To-Use Powerpoint and Excel (Seoul)

Hi~ all.
I'm looking for an English friend interested in How-To-Use PPT and Excel. My major is computer science and work for Kyonggi Univ.
I want improving in my lecture in English. It’s just free and comfortable teaching PPT and Excel, having a cup of coffee or tea.
I'm unavailable during the work week.
