Eposn ABW — there are a lot of words that start with A, but "advanced" is not one I would use. As for Shewe and lulu: I tend to judge the quality of people's answers based on the quality of their work, and, if you are asking about black and white, it can be slim pickins there.
I can understand the drive to get printing asap, but don't get too upset that people don't respond here as fast as places like lulu. Sometimes posts I have made wont show up here for 6-12 hours (and sometimes not at all).
I'd rather make prints than constantly messing with QTR profiles too, but learning the process can teach you a lot about how ink is laid onto paper and can lead to sending more refined image data to the printer.
The best way to use QTR is to build your own profiles and not rely on others people have already created. The supplied profiles might not actually be all that good, and you won't know why your print isn't meeting your expectations and blame the software or paper. There is a lot that can vary from paper to paper, and minor tweaks to some settings can often lead to huge jumps in print quality. Learning what the densities look like at each of the crv creation steps can influence how you build the profile for different papers.
My best advice is to get a used photospectrometer if you don't have one already. Then learn to set your ink limits, cross-over points and linearize your curves for each paper. Starting from scratch isn't very hard for K3 printers, or editing the supplied starter profiles like "UCpk-raw-neut.txt". The Diallo QTR workflow is a good place to start—it doesn't go into all the details, but it is enough to get you off the ground.
