First of all, let me just admit up front that I am a complete idiot. A friend of mine (my partner's boss's wife) has a glamorous art studio in downtown Atlanta. The kitchen, however, is not so glamorous. She hired 5 guys to update her Kitchen with Ikea cabinets and the design they came up with was terrible. The guys had never installed anything Ikea before, so 4 months later, they still had only barely managed to get the cabinets installed (identical to the previous layout). When I saw the mess they had made, she had just fired them, but paid them a total of around 5kl. She'd also had to hire a plumber for $200, an electrician for %1200 and she was really upset. I offered to help and because I am an idiot, didn't set up a price in advance. I redid the entire kitchen, installing the cabinets the correct way, moving the range, built custom cabinets, tore out a set of built in shelves, built a custom enclosure for the refrigerator, re-plumbed and wired the bathroom, installed drop ceiling and pocket door in the bathroom, modified some built-in shelves for the entrance to the bathroom, installed cabinet lighting above, below, and inside cabinets. I painted, hanged drywall, established a water supply shutoff for the floor, rerouted the hot water so they didn't have to get hot water from the basement (4 floors below), I scraped, cleaned, and caulked the windows. The list goes on and on. And that doesn't even mention the custom bar I installed. I also managed the returns of the excess cabinets where she got about 1.5k back. And I did all of this by myself. This is a classic story of why you get agreements in writing in advance. But since I didn't do that, I need some advice. Now, the project is done and she absolutely loves it. But I have no idea what to charge for this or how to organize the charges to make sense. Any advice would be greatly appreciated. Also, how do I estimate the charges? Where do I find what's reasonable in this case? Thanx in advance for your kind consideration.

I've been dreaming of getting an under-mount sink because it is so hard to clean the counter top around the lip of the drop in sink. I am getting new kitchen counter-tops. I kind of know the current cabinets will need to be reinforced or completely redone?? So of course I find there are pros and cons to under-mount sinks. A post from 2017 the first reply was why they don't like under-mount sinks. Anyway when, if, I do go with under-mount I would have it professionally installed. Have "things" opinions, ways to install, changed since 2017? Any suggestions, tips, on what to watch out for? What to ask the installer?
