From Casati, about $1400 for aluminium. Steel $2k+, and quite a bit more for stainless. Top of the line cf would be about $4500, but other carbon designs can be made to measure for less. Considering what people pay for off the rack bikes, one doesn't necessarily have to pay a premium for made to measure. What MtM shops lack in economy of scale/volume, they make up for somewhat with MUCH lower overhead than "name brands."
