Since you are on a budget I'd suggest you go to Academy and get the following:
Game winner waders. They have waders ranging from $70-$160
Federal 3 inch #4 Steel for shells
Puddler pack of decoys and the egg weight Texas rig set.
Then have at it.
Things you might need:
A layout blind
Things you don't necessarily need but will want after you get addicted;
Calls of various brands and types
No calls? When I had access to waterfowl land, I hunted with snake boots, a mallard call, some MOJOs (dove and duck) and some decoys. And a stool to sit on. Only did this for 2 years and only for early teal, but the call and MOJO seemed to work very well.
