I love this idea! Congratulations... for what it's worth most people do not use a wedding planner. We had a huge formal wedding and planned the whole thing without one, so don't stress about that!
I would suggest hiring a caterer because they will be able to give you guidance. They are not nearly as expensive as you would expect. Most caterers will work within your budget and find ways to feed your guests without breaking your budget! If you are willing to have the event on a Sunday, it will be even less expensive.
Suggestions:
- Limit your beverage choices to control costs... beer, wine, champagne (for the toast), water and soft drinks
- Consider a "garden party" during which you get married. Have your guests arrive and the food and drinks available. I would suggest having them arrive at 2:00 and plan on walking over the bridge around 2:30. The ceremony will likely be short, so you can continue your party immediately after. Maybe plan on cutting the cake around 4:00 with your "exit" at 5!
Food thoughts:
- Avoid "dips" b/c they are tough to "hold" and "carry"
- Things on toothpicks and skewers are great!
Meatballs, fruit kebabs, chicken satay, caprese skewers, shrimp, oysters, empanadas, egg rolls, spring rolls, sliders (burgers or pulled pork)
Definitely get some catering quotes. If you have an idea of your budget and find someone you like... they will help you find a way to make it work!
