Restoration Hardware is one of the better stores out there, additionally I'd look at Ikea, depending on the taste/style of your design. Hope this helps you in designing, modifying, and renovating homes!
Also, be sure to add yourself to the directory here on MyREALTY.com under 'Interior Design and Decorators' - this will help you get more business and grow your market presence/brand!
