you might already know about this website..but i LOVED www.theknot.com
it was really helpful to keep things organized, and figure out all i had left to do.
also, this has nothing to do w/ your question, but, however your finances are working,whatever your budget, plan on at least $2,000 more, for things you didnt think of. (and TRUST me, there are a lot of those little things that add up quick) (guestbook, favors, placecard holders, etc.)
