PhD Language Help

I am preparing a PhD dissertation in computer engineering, and the technical content is taking most of my time. I am now worried about the language because some sections sound too complex. I have searched for phd dissertation proofreader writer and found different types of support. What should a PhD student expect from a proofreader? Should they only correct grammar and spelling, or can they also point out unclear sentences? I would appreciate advice from other researchers who have had their technical writing reviewed before submission.
