John, I'm in Seattle but not after your business, just adding info to the thread. I stopped supplying the profiles made here to clients, for many reasons. Unfortunately this business has become brutal, and frankly my profiles would be used more for criticism of the output here for others to use as marketing fodder than anything else.
Additionally, with some papers, the profile becomes obsolete with each batch that comes in.
Provided with the print cost here is a proof on the actual paper, and within reason edits will be made if a disappointing departure from the monitor image.
I have yet to have to do that, though occassional edits and re-proofs have been done simply because the artists desired some changes.
All of this has been working perfectly, the exceptions being for people without calibrated monitors when they prepped their files.
I'd like to add, $200 for a 40x60 is a great price, jump on it, after approving a proof even if you have to pay a little for it.
