I dont know if this helps, but I did my wedding in stages:
1-Actual wedding just my family and 3 of our friends in Vegas
2- One month later wedding celebration/going away party with my family. Held it at a friends house, had a mixed tape as a DJ, my aunts wedding gift was flowers, we borrowed tents from my cousin, borrowed tables from my parents church, chocolate fountain and fruit as a gift from another person, table lines from a friend, and my parents wedding gift was a cheap caterer & Elvis impersonator.
3-in the UK, get together with DH's family at his parents house. Mid-afternoon thing with basically some cheese plates and sausage rolls
4-friend party in the UK- we rented the football club for really cheap and just had a friend's band play. One of our friends bought cake as a gift and we used champagne we got from DH's family for the toast, the rest of the drinks were from a cash bar (i'm cheap).
All in all DH & I spent probably £450 for all 4, with 75% of that being the actual Vegas ceremony and paperwork. My parents spent a little more than £2,000 for the food (for 80 people), Elvis plus an expensive meal, champagne and limo tour of Vegas. Once people knew we were getting married and trying to plan it all ourselves, we were overwhelmed with suggestions of cheap things and volunteered stuff for free. I probably could have kept the budget down if I didn't insist on the candy floss machine from the caterer and my DH would have let me charge his friends £5 at the door (they
were seeing a band
).
I didn't really want anything other than a "let's just sign this paperwork and get it over with" wedding, but my mother wouldn't let me get away with that. It is totally possible though, to have a decent sized wedding for really cheap. If you really don't want it, don't give in, or feel bad, but if it does happen, you aren't too likely to regret it.
