Adjustments to Wordpress website

On our excisting website [login to view URL] we display vacancies. Now we want our editor to be able to place a vacancy on top, above the other vacancies. there should be a setting to tell how many days, or to which date the vacancy should be on top. A vacancy is a post which is linked to the category vacancy. It is displayed on 3 positions: the homepage (only the 5 most recent) on a list of vacancies and on an email template (only most recent vacancies). If a vacancy is marked to be on top it should display on the homepage, on the top of the list of vacancies and on the email template. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Employer will receive exclusive and complete copyrights to all work purchased. (No 3rd party components unless all copyright ramifications are explained AND AGREED TO by the employer on the site per the worker's Worker Legal Agreement). ## Platform Wordpress platform
