Madi,
You have received great advice so far. However, be aware that, first, you really need to create a budget for the food items based on the number of people you plan to serve or the cost can totally skyrocket

(One of the first times I gave a party similar to the one you are planning, I didn't keep a budget and ended up spending over $500 for the food alone and this was back in the early '90's.

I did entertain again for over a year. ) Also be mindful of extra expenses such as the centerpieces or other table decorations, condiments and/or paper products. Luckily for you, women tend to eat less than men, so planning one or two of each appetizer should be enough. If you're hosting your party outside of typical meal hours, five or six types of hors d'oeuvres should be sufficient. If your cocktail party takes place during meal hours, plan to prepare eight to ten types of hors d'oeuvres. That said, I always plan a bit more than my estimates. I also nticipate which small bites will be most popular and prepare more of them than the guidelines suggest. Do add "bulk" items to your menu such as nuts or olives. Finally, don't set the "dessert" items out at the beginning of the party. Instead, as the party is starting to wind down, or you see that you're running out of food, put out the sweets and take away half-empty platters rather than refilling them.
That said, when I am giving a party,
I focus on hors d'oeuvres that can be made ahead of time, unless I have an assistant in my kitchen. I always want to look the cool, elegant, calm hostess, not a harried individual who has no time for her guests because she is so busy running between the kitchen and serving table. Personally, for my menu, I’d think a little “retro.” (That’s a bit trendy these days, too.) Just don’t go back to the fifties/sixties when the recipes starred deviled ham, cream cheese, and dried onion soup mix.
Here are some of my recipe suggestions many from ‘80’s
Canadian Living so they shouldn’t be overly common here in Louisville. If you decide you want any of the recipes, please PM me. (Recipes with an asterisk may be made ahead. I have omitted salt and pepper when listing ingredients.)

Gee, putting this post together has been so much fun, I think I’ll have to have one of these myself, next month.
I’ll leave Stephen to suggest ideas for cocktails and Brad for punch. When I do this, I’ll probably just wimp out and have several wines available. I think I’ll let David DuB. help me with that.
