HTML/CSS Developer/Designer-Header Drop Down and Mobile Header Rework

Looking for a developer/designer for micro project. We are looking to add a drop down in the header of a webpage that shows a list of four services, when one of the services is selected in the dropdown, the user is directed to the Service page and the section they clicked on(see attached for more clarification).

We also need the mobile header reworked to be more user friendly, maybe a hamburger menu.
