detachable wedding dress

Hi Everyone
My beautiful daughter and partner are getting married so a wedding we must plan ?
They are wanting a place where they can have a garden ceremony, photos, Canapé cocktail hour and reception with food and drinks for 40 people. And if possable accomodation for at least the brides plz.
Must be very romantic, lots of flowers ect.
Anywhere in the Brisbane, Gold Coast or Sunshine Coast regions.
Budget for the whole wedding including dresses is $10,000 so needless to say I'd greatly appreciate any info, recommendations ect on how I can create a romantic beautiful wedding for my girls to remember always with love and a smile. detachable wedding dress
Also needing a guide on prices for videographer, makeup & hair for the 2 brides, celebrant, and someone who can make a fake cake to look like the one in the photo at a reasonable price.
Thank you
Kindest Regards
