It may or may not hurt you. But since you are playing against newbies it's probably not going to make a huge difference. As Jimulacrum said, the best thing you can do is make them deal. It will boost there confidence massivly plus if you were to play in a different environment you dealing every hand for them may not be appropriate.
If making the game flow faster is your main objective here, something we have done in the past is have two decks - One red, one blue for example
Player one deals out the entire hand - upon finishing the hand he gathers up the cards and shuffles them and passed them to Player three.
Once the first hand is over player two starts dealing with the second deck. Once that hand is over he passes the cards to player four and so on.
Obviously you don't want to risk two decks getting mixed but overall this really speeds up the amount of hands you get to see
