How do people afford this?

We are doing a Sunday brunch wedding with no cocktail hour. The venue allows us to bring our own alcohol, I am ordering my dress online from an inexpensive store as its not a 'traditional' wedding dress, I'm learning to do my own makeup (lessons are $75 vs $250 for artist day of), I have a small wedding under 50 ppl of just our most favourite people. We are aprox. $20,000 but that's because the venue we've booked was expensive, and is an all inclusive pkg (officiant, DJ, caterer, decor as its an old barn and we are using their rustic decorations and minimal additional) small wedding party and asking our wedding party to pay for their dresses/suits; but I/we are so excited for our brunch wedding and then heading off to our honeymoon!!! You can do it, but it will take a lot of researching and shopping online and some DIY. I'm happy to share anything I've learned already. Feel free to reach out. I'm also in Ontario so I can give you a few places that are all inclusive I've looked into, depending on where you are. Good luck!!!
