Interior designers typically charge hourly. Most designers will meet with you to learn about the project and your needs. Once they have determined if the project is a good fit for them they will put together a proposal based on what they project as the time required for the services you are looking for. The proposal usually states the number of concepts they include in the price and an hourly rate for the time they spend preparing additional concepts or selections. Good designers are always good listeners, so pay attention to your first interactions to get a feel for how well they listen to you.
