The reliable way to hire a pro

Just moved into a new home and I'm really not loving the colour of the laminate floors. Is it possible to lay vinyl flooring right on top of the laminate? Asking to know if can avoid taking off the baseboards and removing the laminate.

The basement of our house has been professionally water proofed and has a sump pump. This wet spring small amounts of water appear to be coming through the walls .

How do I go about adding a dishwasher to my kitchen that never previously had one? I'm more than willing to have my kitchen drawers (where I want the dishwasher to go) be remove and have the dishwasher go there. But, does that mean I need to involve some sort of reno/demolition people? Once they are done, then do I need an electrician and a plumber to hook up the dishwasher? Would love to get some input on how to begin this project, the order of what to do/when to do it, and what to watch out for. Also, any input on what to look for in a dishwasher and any brands/things to stay away from? This is my first time buying a dishwasher. Thank you in advance for taking out your time to answer my questions. All advice is really appreciated!
