We did our wedding for 80 day guests and 100 ish evening for just under 7000 5 years ago.
We were lucky with the reception venue, it was their first year so cost 1500 exclusive use (barn). Our ceremony venue was a town hall but a very chapel like one. We decorated with home made bunting.
Flowers were done by a friend of a friend, not free at all but she did them as a side hobby so cheaper and I had wild flowers and sunflowers which is cheaper than Roses etc.
Cake was made as a wedding present by a family member.
Catering was a hog roast with bowls of potatoes/salads and dessert.
We hired a bar and got a very reasonable drink package (10.20 for welcome drink (pimms) half a bottle of wine per person and toast drink).
Dh is in a band so he had friends play out first dance song, we had a spotify play list for everything else and hired speakers from a local music studio.
We hired lawn games etc for entertainment.
We did m and s buffet food for the evening.
My dress was 700 though my mum bought it for me, bridesmaid paid half their dresses (I know this isn't a popular option on mn).
DH bought his suit but the groomsmen hired.
We did the decor ourselves (hessian table runners, mil made table cloths, jam jars, candles etc)
We shopped around for chair and table hire.
Our photographer was a family member so we paid half price.
So many people have said it was the beat wedding they'd been to. We were very lucky with family input I know.
