BOSTON – Security officers won’t be the only professionals coming to Boston in unprecedented numbers for the Democratic National Convention.

Practitioners of the world’s oldest profession are seeking reinforcements to help service some of the 35,000 visitors — plus untold numbers of police reinforcements — expected in the coming week when Democrats name Sen. John Kerry their presidential candidate.

“Every convention brings in more people, and women fly in from all over the country to work it,” said Robyn Few, a prostitute on probation who runs the Sex Workers Outreach Project, an advocacy group.

“There will be girls from California and from the South in Boston this week,” she said. “I hope a lot of women make a lot of money and make a lot of men really happy.”

While Boston has played host to a number of conventions, a national political convention draws larger crowds than the city is accustomed to and security for the event is said to be unprecedented amid terrorism concerns.

For weeks, escort services have plastered advertisements in magazines and on the Internet asking women to work the convention.

Even local strip clubs are putting out the word that more women are needed.

“We are looking for more girls right now,” said Frank Caswell, who runs the Foxy Lady club outside Boston. “Obviously, hospitality and beauty are expected and the girls must bring something that is enticing to see.”

Local agencies said they charge anywhere from $200 an hour for a little company in a delegate’s hotel room; rates at national agencies can be five times that much.

Several sex workers said political conventions were often particularly lucrative. Democratic organizers wanted to point out that many delegates are bringing their families.

“This really is a G-rated event,” said DNC spokeswoman Mariellen Burns
