We did this for our wedding so maybe some ideas will help. We printed invites via an online service, nothing super fancy just simple and nice. We cooked the main dishes (smoked whole prime rib and Low Country Boil (frogmoore stew if you are in South Carolina) and did some smoked jalapeno poppers (Atomic Buffalo Turds), with sourdough bread bowl's filled with spinach and artichoke dip. We had some guests that brought a few of their favorite sides as well. We hosted it in our backyard and rented chairs and a large canopy thing in case of rain. I think the cost was in the 4k range at that point. It turned out perfect and we made it more of a backyard bbq which kept guests stress down because no need for suits etc.. for attire. The invites were awesome, you might be able to find the template online by searching for "Eat, Drink, and Be Married". There was definitely a good deal of stress getting everything ready, but overall that removed the stress of needing to coordinate others and worry about vendors being on-time and doing what they said they would. For me, it was the perfect way to do it, without the pomp and circumstance, surrounded by good friends and family, eating amazing food, and enjoying the company while celebrating the newlyweds (us!).
