Budget #1 - this will determine what type of wedding you can have and how many people you can invite.
Once you have your budget think top of funnel, what type of wedding (ceremony and reception) do you want? Beach, church, etc. Then start looking at venues, I suggest to limit to 3 choices.
Then start thinking about your numbers, this will really help define the venue(s) once you get quotes, compare against your budget.
Once you have your venue(s), the fun starts! You get to refine your invite list, choose food/drink, etc.
There are some excellent wedding apps which are really cheap to buy and are very helpful in a run down of what to do and how your spend is going against the budget.
I'm an excel nerd, so I built my own, but friends have bought wedding apps for a couple of dollars with no regrets.
My only other advice is don't look at too many options! I had a rule of 3 (maximum of looking at 3 florists, 3 food options, etc) so it didn't become overwhelming.
Have fun!
