We used the Container Store. They have a well constructed product, ELFA, that is adjustable, comes in different finishes and can be customized to a tee. You can view photos on their website and work with one of their specialists to help plan your spaces. The consulting, planning and pricing is free. They have the right products for bedroom closets, office spaces, kitchen pantries and garage spaces.
We have a Lantana model with an odd shaped master closet. The Container Store did a great job working with us to use every inch of space.
I posted some photos under a previous thread:
