machlin,
Welcome aboard!
The link above will take you to the largest network of firearms trainers in the USA. There's a locator tool at the site to help you find out if any are teaching near you, as well as a list of available classes and class descriptions.
Taking on the training/range outing of a large group of neophyte shooters is not something to be taken lightly. No matter how good an instructor/trainer you are, with multiple new shooters on the range, you will need adequate, capable supervision to make sure no one does unsafe things. I've been there... and I prefer one on one with a new shooter.
hth,
