I've personally authored multiple peer-reviewed articles in high-impact journals (Cell, Neuron, etc.), so I'm likely familiar with the style and quality requirements that you need. I've typically been one of the few native English speakers/writers in the places I've worked, so I'm very practiced in editing papers from non-native speakers on subjects about which I may know little to nothing. I should note that I generally try to get papers edited and returned to colleagues by the next day, so that would be the goal here as well. This can be particularly important when the original writing is, in places, ambiguous and a short discussion is needed to completely clarify meaning.
I should note that if you need help replying to reviewer comments that that's something I generally help out with as well (I would consider that part of the package).
Feel free to contact me if you have any questions,
