Householders in Newport could cash in on renting out their homes to golf tourists for the 2010 Ryder Cup, it has been claimed.
The 2010 Ryder Cup is being staged at Newport's Celtic Manor
Wales rugby star Alix Popham has set up his own business to act as an agent between homeowners and tourists.
Thousands are expected to make the journey to the city, with most demand expected from visiting Americans.
The Welsh assembly government said a range of accommodation providers across the region could benefit from the Cup.
Newport-born Mr Popham, who plays for the Llanelli Scarlets, said the first 25 householders had registered for his service.
The householder will pay him £100 to advertise on his website, but he claims they stand to make thousands from the tournament.
"I got the idea from a friend in Scotland," he told BBC News.
"It's just to supply the service because I knew there isn't enough accommodation.

"And there has been lots of interest. I've got another 15 houses to put up today and I've already had 10 bookings."
Mr Popham said he expected the majority of the bookings to come from American golf fans.
"People can either offer a B&B where they let people stay in their homes while they are there or they can offer the whole house while they take a holiday," he explained.
"A nice clean tidy house within 15 miles of the Celtic Manor resort could see £2,000 per double bedroom."
An assembly government spokesman said it was working with Newport as host city to play a "unique role" to realise the Ryder Cup's full potential.
"In addition, we are currently working with a range of different accommodation providers to cater for the complete needs of visitors and spectators to the event," said the spokesman.
"Given the excellent transport links across Wales, this accommodation offer will undoubtedly include facilities along the M4 corridor and, for example, at many excellent venues across the south Wales valleys."
He said the event would bring a "wide variety" of business and commercial opportunities.
