Biglips, I love your approach to your wedding :o
Here's my wedding experience.
We married last spring with a total budget of £1000.
The format was: wedding on the Thursday before Good Friday (cheaper reg office fees, and everyone able to take day off work - we checked before finalizing the date). Lunch for very close family and friends (about £400), then the wedding, then cakes and drinks at our not-very-big-house (= Tardis: it's amazing how many people you can squeeze in) for all comers.
We had masses of help, people were falling over themselves to join in! Wedding cars = friends cars which they drove. Friends made my bouquet, my dress/coat combo, buttonholes, took photos, made cakes, brought drinks, and so on. I think that because so many guests had been involved in the preparations, they felt more involved in the wedding.
We had masses of fun! :o
Loads of guests said this was the jolliest wedding they'd been to. Less formality seems to create real fun!!
(I was married before, and had the full posh, smart wedding works. It was chic, but far less joyous).
