Ayn Grinstein, 27, runs errands for L.A.'s needy sybarites. Those looking for someone to fetch diamonds from a bank vault, locate a five-pound avocado or rustle up female mud wrestlers can call Grinstein's Services Unlimited in Beverly Hills. "We do the work; you take the credit," promises Ayn, who cheerfully operates as a Jill-of-all-trades planning parties, coordinating wardrobes and tracking down the impossible. She depends on a staff of five and a plump Rolodex full of contacts. "We do almost anything our clients don't have time to do," she says. Services Unlimited answers Keenan Wynn's fan mail, takes care of WKRP star Howard Hesseman's cleaning and has just sold Donny (Happy Days) Most's 1974 Jensen-Healey sports car. When artist David Hockney is in town, Grinstein fills his house with fresh flowers. Bookkeeping, personal household management and errands cost up to $20 an hour or a $1,200-a-month retainer. This year Grinstein expects td gross $100,000. Says one satisfied customer, Lois Magnin of the clothing store family: "Ayn has made a business out of being a nice girl from a nice family who does things the way you would." A native of L.A., Grinstein was born to a truck salesman and an architect who are also co-owners of the tony West Hollywood art gallery Gemini G.E.L. Bored with teaching preschoolers after graduating from USC with a degree in sociology, Ayn joined two friends to launch a service firm; she bought them out in 1978. Her varied clientele keeps Grinstein's phone ringing after hours at her rented Brentwood home—an intrusion she has discouraged ever since one lonely customer called at 3 a.m. just to chat. "I'm not a nine-to-five person," notes Ayn, "but I got more than I bargained for."
