Company site amendments - Consultancy required

We requested changes to be made to our company site to edit the department/location filters for candidates who are looking at roles in our careers section. We were advised that editing these basic components would require consultancy work. We would prefer to have the ability to make these adjustments on our end as and when required rather than having to pay and wait whilst this goes through consultancy, as we believe these adjustments should be relatively simple within the backend.
