Need to edit header

Is there a way to edit the header in Decree Pro? It is the only item not shown in any current posts. I am not satisfied with the position of the title/subhead and logo and in addition, there does not seem to be a way to edit the built=in "free consultation" button and connect a form to that. VERY FRUSTRATING. I upgraded to Pro for these options and cannot even find a template for the header anyqhere.
