One initiative the team has developed includes a charity auction, with a selection of unique or unusual items up for grabs on Trade Me by searching GT Limo. Gilmour has donated two of the auction lots.
"It would be fair to say I'm the country's most widely recognised marriage celebrant, so a wedding with me certainly can be a wedding with a difference."
To complement the big day, there are two jewellery lots available as part of the charity auction.
The first is the chance to bid on wedding jewellery, courtesy of Charles Lewis Fine Jewellery, to the value of $3000.
Its team of experts are specialists in designing and manufacturing highest quality rings and jewellery sets, ensuring your jewellery is an eye-catching addition to your big day or any occasion.
And just in time for Christmas is the chance to buy $1000 value of items from the Michael John Jewellery designer collection, specialist in high-end fashion modern classic jewellery.
Other items include a set of new passenger tyres courtesy of the GT Limo sponsor, GT Radial tyres, and the opportunity for your car to feature in Driven's Me and My Car column.
Gilmour is also donating a show to the auction effort.
"It could be a show just for yourself and your special someone, a work social club event or after-dinner comedian," he said.
