West One will fly the group to Vegas where they will spend three nights at the Bellagio hotel famous for its high limits poker rooms.
The prize includes premium economy return flights and gives the winning introducers entry to conferences, seminars and exhibitions laid on by West One Loans while the group is in Las Vegas.
The winners will be chosen via a random prize draw and notified by email.
Duncan Kreeger, chairman of West One Loans, said: “The brokers we deal with work exceptionally hard. We value our relationships with them very highly. This is our way of saying thank you and giving them an opportunity to let their hair down.
“In total there will be fifteen of us going - I’m thinking of dubbing the trip Ocean’s Fifteen!”
Kreeger adds however that it isn’t all play.
He said: “We’ll be laying on a series of informative seminars, conferences and exhibitions where introducers can debate industry issues and share their knowledge.
“It will also give us the opportunity to tell them more about West One, the products we offer, and some of our ambitious plans for the future.
“We hope this will get more people talking about West One. It’s a great opportunity for us to showcase our qualities. It’s already created quite a buzz within the industry.”
