What are some good custom wedding dress makers?

I found my dream wedding dress and am trying to have it made for less money. I have only found 2 websites for businesses that will make a dress from scratch. All the others that I found when I searched for anything similar to "custom wedding dress" were places that make their own styles and sell them just like a designer does. Any suggestions?? If it's near Dallas, TX that would be even better, but anywhere in the continental US would be fine with me!
