fly fishing etc.

I'm going to Kodiak Alaska fishing around August/ September. I want
to get back into fly fishing. I haven't fly fished in years and I
need to get some gear. Since this will be my first time in years can
somebody suggest where I can get some equipment for a first timer. I
need to get some waders for fly fishing and also working the rivers
with spinners?

Since I'm only going to be trying this for about a week I don't want
to spend a bunch of money.

Any ideas about how I should equip myself?
