Hi, i don’t give skype lesson but i have a didactic channel on you tube and a dedicated facebook group.
The channel has only a few videos because it’s new, but i constantly post videos about techiniques, theory (in particular applicated to guitar) and about sound.
In addition to this, you can ask for particular lessons and I’ll give them priority. (For example a guy from bangladesh asked me a lesson about warm up exercises, and I posted it in a few days)
If you are intrested look on my profile: there are links to fb and yt
