Strategizing about a simple kitchen/bath remodel

We are thinking of doing a simple remodel to our kitchen and bathrooms. We would not be changing the layout of the spaces, but just replacing countertops, appliances, sinks, maybe painting cabinets and potentially floors just to make the spaces a bit more modern/to our taste. We are challenged when it comes to design and also don't have the time to coordinate everything ourselves. I'm trying to determine who the right person is to hire for this kind of project - someone to give us design ideas and then coordinate the actual implementation. I would love any suggestions from folks who have done something similar.
