I didn’t read a lot of this thread, but I’m putting my two cents in because I planned my best friends very extravagant wedding, so this sounds a little simpler.
I’m going to concur with what someone else said - do NOT invite people you don’t want to share the wedding with to the wedding. Invite people you truly enjoy spending time with.
Do not bow down to anyone’s wishes. This is YOUR day.
The iPod idea is GREAT. I love it. Wedding music sucks anyway. Are you a Star Wars fan? A friend of mine walked down the aisle to the Imperial March - I suggest picking a song you really love that sums you and your relationship (or that you just really like) up to walk down the aisle to.
Catering isn’t actually that bad assuming you know you like the food from that place. If you like barbecue, get a barbecue place to come cater it. However, if you’ve got friends who are vegetarian that you want to come there, make allowances for that - not HUGE allowances, but make sure there’s veggies and stuff. Most carnivores will eat it too. It’s something a gracious host does.
As for the Bic idea, I kinda like it, but as you said, it seems kinda classless. If you decide not to go that route, my friends got match books printed up for relatively cheap with their names and wedding date. You can do this online - and it’s classy looking when it’s done.
I also like the Web site idea - if you don’t know what you’re doing, I’m a Web designer and I would be happy to set it up for you as a wedding gift. If you don’t want to do the Web site thing, that’s cool, too. It’s perfectly acceptable to put all of that information on the invite. I would say something like “The bride and groom request that attendees dress in casual, comfortable clothing.”
Port a potties are a good idea. Most likely your water or sewage company could refer you to a good, respectable place. They can run on the pricy side but they’re usually pretty reasonable.
Unless you live somewhere where July is overbearingly cold, I suggest getting a large EZ-up or something instead of a tent. Tents are HOT. You can usually book them from the same place you would book a tent from - check into it, and see if they would allow you to do something like set up for an EZ up awning and change to a tent in the event of inclement weather like rain or wind.
If you have a lot of friends, see if some of them could come over and help you with things. I got a party of friends together with some munchies and sodas, and we folded self-printed wedding invites and programs ourselves. It was actually kind of fun. I have no idea where you are located, but if it’s near where a bunch of Dopers are I’m willing to bet some of us would come over and help.
Also, if you want lots of pictures, we got disposable cameras and put a few on each table with instructions for the guests to take pictures and leave them with the family so that we could put together a scrap book. It turned out great - and if no one you know has a penchant for scrapbooking, I’m willing to bet someone on the Dope does (I do, so there’s bound to be someone else).
Most importantly, CALM DOWN. You have six months to plan this, and at least four of that is going to be getting the petty details settled. Don’t cave to anyone else - this is YOUR day. You’re going to be getting married to the person you’ll be spending the rest of your life with. You want it to be perfect for YOU, not your family.
Congratulations, by the way.
It’s not as hard as it seems - make a list and it makes it seem 10x easier because you can just cross off stuff you’ve done.
Best wishes.
