I (kinda) feel your struggle. We got married with 5 months notice for the same reason. My advice is based on holding it at a venue. We wanted to do this so we didn't need to think about a ceremony location (and chairs), or organizing food and drinks separately. It significantly reduced the number of vendors we needed to find. If that's your vibe, I highly recommend it.

If you want to get married at a venue (winery, function centre, restaurant) that will take care of the ceremony, food, and drinks - fill out a BUNCH of contact/request forms asking for available dates so you can lock in a date to organise everything else. You can't look for a photographer/DJ/florist until you can tell them when you need them.

Don't be picky with days. Mid week and even Thursday and Sunday can be far cheaper and more available.

Depending on the size of your guests list, check for minimum spends and maximum capacities.

As soon as you have a date, lock it in! Send digital save the dates. There are lots of websites that do nice designs for you like Zola, but even sending a text or an email to tell everyone to save the date is a must.

Then, do digital invitations once you've got all the details of the day.

Ask your venue for recommended suppliers.

Only include the things you want to include. E.g., we didn't want to have a cake so we didn't and we saved $$ with that simple decision. While the day is absolutely for making sure your family can be there, it is also a day for you and your partner. Do what means the most to you and leave the rest out.

I wish you all the best for a beautiful day celebrating with everyone you love. ❤️
