Hi,
I am Ian a developer based in Ireland, I run these type of courses normally through PPH (review links can be sent) teaching wordpress to website owners through skype or teamviewer.
I am an elegant themes licence holder, so work with Divi quite a lot, let me know if you are using 2.3 version (old) or 2.4 version (new) as the set up varies between the two versions.
The issue of back ups and transfers is actually quite an easy one once you have the right tools and have seen how to do.
Price is per hour, I always recommend to client they do in 1 hour sessions only as after that you tend to lose some of the benefit.
Any questions or queries, just let me know or my skype is ijcire.
Regards
Ian
