Are you familiar with OTAN and CALPRO?  Both  organizations offer free online trainings.  OTAN focuses on technology related trainings. They are usually about an hour and a half  long and done online with a telephone so you can hear what the faciliator is saying. You can also ask questions by using the phone or typing them in.

CALPRO online workshops are usually run more like a mini-online class.
