What we did (my first wedding and his 2nd, but he had a fairly big wedding the first time) was to have an immediate family only ceremony, honeymoon and informal "un-reception" after our trip with everyone else.
I think you could still have a big wedding if that suits you, but consider other options. For example, I rented a popular venue on a weekday and got it for "conference room" rates. I mainly needed the indoor space for food and bad weather contingency. I used a photographer that did calendars and other work and was looking to get into weddings. He did a good job, we got a beautiful album and all our negatives, for $400. That sort of thing. Spend more on what's most important. If the personalized napkins aren't important to you, go to Party City and buy the plain ones in your colors. I found that any time I could avoid the word "wedding" it was less expensive. You can also check out community parks and buildings. In our area, many historic buildings are for rent, for less than at a big hotel or traditional "wedding venue". Or hey, just have the reception in the social hall of the church.
I'd also weigh how important it would be for Aunt Edna to attend. Maybe in the name of family peace you compromise somewhere to have a bigger guest list, especially if they all missed out the first time.
Hope that helps. We paid for everything ourselves, too.
