What you want to do is quite possible.
Probably the most important thing you need is some land where there are turkeys. Turkey hunting often requires more area than some other kinds of hunting.
As far as equipment, get a box call. That's the basic call everyone uses, and it's the easiest to master. Any of the videos on the market will show you what a turkey sounds like. Don't get too wrapped up in making lots of different kinds of calls.
You also may want a turkey choke for your shotgun, and some sights- you'll be aiming your shotgun like a rifle, so, you may want some sights or a red dot or a scope on the gun.
A decoy isn't mandatory, but it can help. That, and some camo clothing, a facemask, a pad to sit on, and you're ready to go.
