Simple alternative weddings

Anyone want to share their ideas? We’re looking to do something small (family only), intimate, possibly just a ceremony and champagne toast to send us off? We’re buying a house and can’t spend the money right now! We’d like to do a bigger anniversary party later. We don’t want to marry at the court house and our pastor will officiate. How do we go about this in a way that is classy and doesn’t offend?
