Hi rolexboy,
Between the 11k and 19k, you might want to align the material intended to use, where is it from, dimension and its finishes. Its 8k different! I can put up wall covering for the whole house!
For eg, to design a tv console, what is the material use, how long its the console etc. Also, what type of finishes they give it to you.
All this has to be stated clearly, perhaps in 3D sketches to avoid and misunderstanding, which most commonly happen.
