Congrats! I'm sure it will turn out well
I generally buy my hops from my LHBS, unless I'm buying in bulk (in which case I've used freshops, hops direct, and hoptech) or it's something they don't have.
There are a number of threads here about different online suppliers (Norhern Brewer, Midwest Homebrew, Austin Homebrew suppley, morebeer, etc.). If you don't have an LHBS, check them out.
