Wedding Planning!

Okay so I have been planning my wedding since I was like 9 years old. I've been engaged for almost a month now! Im so excited to start officially planning. I feel like there's so much to do but I don't even know where to start or when to start! We've decided to have our wedding in the fall of 2020. We're on a budget and we're paying for our wedding 100% by ourselves so we wanted to give plenty of time to save up and get everything over time. Wanting to go with a kind of rustic theme (so unoriginal I know). Anyone have any ideas? Any DIY tips to help save money? Pictures of your weddings are welcomed, I looooove to look at wedding pictures 😂 Also our wedding won't be huge, maybe 50-100 people
