Talk Money
Designers’ fee structures vary. Some charge by the hour for designing and overseeing a project. Those who work in a showroom may charge a retainer, then deduct that cost from the products you purchase through the showroom.

Labor arrangements vary, too. Some designers provide a contractor, while others only recommend a contractor, leaving it up to you to make the arrangements. In some cases, a designer may be willing to draw up a plan for your kitchen or bath, and then let you provide labor and installation.
 
Get It in Writing
When you’re getting ready to sign an agreement with a designer, make sure it covers all the services you’re expecting. Do you want the designer to review all bids from contractors and suppliers? Do you want the designer to help you shop for products? Will the designer troubleshoot if there’s a construction problem or product delay? Does the agreement include an opt-out clause if circumstances change or problems develop? Don’t be afraid to ask for one.

Follow Up
Once the project starts, keep the lines of communication open. Contact your designer when questions or concerns arise, and don’t hesitate to speak up if you don’t think the project is going the way you thought it would. The earlier you address problems, the better the chance they can be solved. Remember that the designer has a stake in the success of your project, too.
