I think it depends on what sort of wedding you want. DH and I are fairly weird quirky, so we didn't bother with most of it. I wore an ordinary dress, DH wore a suit which then got used for work, I did the flowers myself, we wrote out place names ourselves on bits of paper, my mum made the cake, etc. No favours, no disco, no photographer, no hairdresser, no wedding cars, no bridesmaids, no best man, no speeches, no music, no entertainment, no buttonholes. We just spent the money on a good quality meal and drinks for everyone. We also had the wedding itself separately, so there was no worry about getting from the register office to the venue.
The only downside is that I found the register office wedding itself to be pretty crap (it lasts about a minute and I'm used to church services going for about an hour including sermon, hymns etc), but then that's life.
I'd start by making a list of what, if anything, actually matters to you, and use that as a touchpoint. Anything else on top of that is probably just marketing and can be ignored.
