I am having my invitations done by computer in a calligraphy font. The invitations don't have an inner envelope, and my hall does french seating, so we don't need place cards, and I certainly don't have the time and energy these days... lol... we figured it was worth the $1 an envelope.
Beach pics are difficult. If there is not enough definition in the background, sand can blend into water can blend into sky. The photographer has to be really good to underexpose the sky to make it as dark as possible (w/a polorizing filter to accent the clouds). Also, the beaches along the Bay aren't really too interesting (no waves) unless you get one w/sandbars or land across the way. I can't think of any with reeds + dunes, which would be nice. The closest for you might be Florence Beach in Massapequa, but don't forget the people in the background. You might want to schedule a separate day for just the two of you to go over to Fire Island for the kind of pictures you might be looking for.
