I've been searching the web to no avail. Does anyone know if I can hire a professional decorator to decorate my house with MY items. I don't need to buy new things or paint. Just not good at displaying my things as well as I could be. Any idea on cost? I'm in Los Angeles
of course you can. Ask around and see if anyone knows a good decorator in your area. Then check their references and find out what they charge per hour. I go out for consultations all the time. You may also want to research local design schools and see if there are any upper class students who would like to take on your project. They will often work on your home for a nominal fee as part of a class project.
In addition to the things others have said, you might try the design center in LA. Many designers and decorators list themselves there. Also many tradesmen have connections to designers and decorators. I have even seen business cards posted at the local paint store.
It sounds like you need a decorator who specializes in accessorizing. A designer might not want to tackle something of this scope, but lots of decorators charge by the hour to come and help you arrange your things. There may be a minimum charge for two or three hours, so make sure you have enough to keep them busy. You can also make a list of questions you would like answered for future projects or ideas for additional things the room may need.
