Firstly, you don't need to invite everyone that you think you need to. If you keep it really small, then that is your excuse for teh sniffly people who think they should have got an invitation.
Don't pay for the alcohol at all - that really tots up!
Don't bother with a photographer, get someone you know who is good with a camera toset up a few formal ones, and I agree with someone else that disposible cameras on teh tables works well - make sure you add a little note to tell people to hand them to hte best man or something so they dont take em home!
Other thing you could do is just have an evening party - i.e. no food. You could get married, have a really small meal out iwth just parents/kids and best man/bridesmaid etc. Then a disco type thing in teh evening in local town hall or the like.
Get your dress out of BHS or Monsoon or something - OR go for soemthing more unconventional - i.e. not white, or a trouser suit ro soemthing. Soemthing yo could potentially wear again. Do you know
Keep flowers simple too - they cost a fortune if you get the poncy ones. If you know someone with a nice garden, depending on time of year, ask them to make your bouquets - basic bunch of flowers wrapped ina ribbon - nothing too flash.
Make your own veil/tiara if you are any good at crafts. If not, borriow or buy. Same applies to the wedding dress actually - borrow from a friend.
Cake - buy out of marks and spencers and go into hobby craft for little flowers etc to decorate.
My wedding cost under £10k and I don't really regret it as it was lovely. But TBH, if I was doing it again, I would just go for a small meal and big party in the evening. That si what we do wtih christenings.
DONT get into debt for it. Its better to save up and do it cheap than be paying for it for years. That was the best decision that I made (we waited til we could pay it all - my parents also contributed too)
Do you know anyone witha nice garden? For your pics. And anyone with a nice car who could shauffeur you for hte day as a favour.
I like plain things, so the above ideas would suit my taste, but if you want to go all out (i.e. big white wedding style - then the secret is definately second hand where possible).
A good site - not sure if still running is confetti.com
