You may want to take a look at TruStile doors. They make real wood and solid core doors. Their solid core doors have very crisp edges like those that would be found on real wood doors. Here is a link that might be useful: Trustile

If you have a tax id# your best bet is a wholesaler. If you have a Garden Ridge, Jeffrey Alan's , Homegoods, or Tuesdsy Morning, they might be worth the effort. Home stores, also~Z Gallerie, Arhaus, RestorationHardware, but you might pay more.

I don't usually weigh in on discussions like this, because mostly the finer points of decor are lost on me. In my world, kitchens are mostly about utility: how well can I cook there? And the first thing I thought when I saw that countertop was something utilitarian: "If I were changing the disc on my food mill and laid the hardware down on that counter, how would I ever find it again?" What's great about that counter is that you could cook on it for weeks and not bother to wipe it down. It would never look dirty. In all fairness, from a distance it actually looks kind of nice. And I agree that a more rational neutral backsplash would be a vast improvement, especially from that same distance. The idea of a black or very dark backsplash makes me feel slightly claustrophobic, but whatever. Up close, IMO busy just brushes the surface. I didn't know Mother Nature ever made granite like that, but if she did, she's probably down at her local pub right now, weeping quietly and muttering "I'm so, so sorry" again and again over her third bourbon. As for the backsplash itself, I just have no words beyond "wow." I think it might even surpass the 1970s fake brick on the backsplash in one of my rental houses. You are NOT out of your mind, IMO. Follow your instincts. PS - you needn't apologize for your English. It's way better than that of many native English speakers on the net. I wish I could write in other languages as well as you write in English.

Do you trust your contractor? If yes, allow him the freedom to do the best job he can for you, using his favorite products. If no, find a different contractor you can trust. Familiarity with products and suppliers allows a contractor to deliver consistent results. Occasionally, there will be a manufacturing or storage issue with paint, and if the user knows how the product should perform, the problem will be obvious. However, if he is working with a new product, he may just continue working and hoping that the problems will go away as the product cures. When it doesn't resolve itself, the contractor has lost time and money and now has a problem surface to correct before proceeding. All the major paint manufacturers sell a range of products, aimed at different markets, different price points, and different quality levels. The top line from any major manufacturer will be more than adequate for your purposes. A successful paint job is not just the product used, instead it is a combination of product, prep work, tools and workmanship. If you stay towards the top of the range in all those aspects, the final result will be good. Go low end on any component and the final result will not be satisfactory.
