Take a course in person from a reputable trainer, they can be found at any shooting range or ask and you will get refered. online is worst then the ten minute classes they give here in florida at gunshows,

carrying concealed is tricky business, take a basic NRA pistol class offered in every state , this will cover you for Va, Az, Fl right instructor maybe Utah, they are all very easy to get on your own once you have the basic pistol class, get your fingerprints at the local sheriff or police dept and you are good to go with a check to cover the processing fee's
I have been trained by the best, I would not want you in the same room during a shooting with a person who only had a on-line training course as your only level of training, we would both go to jail. even without me being there, when you get arrested and you will, and you tell them this is your training you will not make bail

heck florida only requires a basic hunter safety course or military discharge and/or NRA pistol class

do this right
