Adjusting header on purchased wordpress theme

Job Description

We are looking for someone with advanced CSS skills to be able to completely alter the header of a purchased theme to match previous work that was done. The logo on the theme alters its size responsively when the page is scrolled down, and we're interested in maintaining that feeling amidst the other adjustments. The theme comes with 3 or 4 different header variations that can be applied to different pages, and so it will be a process of adjusting each of them.
