I just looked into having custom closets installed. I did not price California Closets, though I have heard they are very good but a bit pricey.
I did have someone from a local, very reputable company called Storganize come out and take a look at our space. They were very helpful and came up with a great design. I am still trying to decide if we want to do this -- as it is still quite an investment. I also had a man come out that I found on the Angie's List referral system and his price was almost exactly what Storganize was (Storganize was actually a little cheaper and had a much better design.)
We tried going to Ikea actually just last Friday to see if we could put together something cheaper. We were pulling our hair out at the design computer, and one of the guys who worked there said that the Ikea closets are better for walk-in closets or flat walls where you want to add closets, but not reach-in closets, which is everything we have. We did buy something for our laundry room and that went together quickly, so I think the quality and price are fine -- just not for our reach-in closets.
Storganize's number is ###-###-#### and I worked with a designer named Jeana (pronounced "Gina.") Their website is storganize.com. I also just found a coupon for a $50 gift certificate to a fine Twin Cities restaurant if you have them come out for a free consultation. I am going to use one of these coupons, but I have two. You can have one (I can mail it to you or you can pick it up) but it expires 9/15 so let me know right away.
Anyway, hope some of this is helpful. We are going through the same thing right now trying to decide what to do. Feel free to e-mail me if you want to know more.
Take care,
K.
