Advanced PHP Project - Feature addition - Private for mukapu

I need the following features on one of my website: Feature 1: I need you to add one more feature to the Business Directory script. The feature should allow the administrator to set a date for listings expiration. For example, the listing never expires, the listing expires in 1 year, 2 years, 5 years, etc. The default choice will be that the listing "never expires". Expires: Never 1 year 2 years 5 years Other* *If OTHER is picked then admin enter the date the listing will expires. Feature 2: Allow the administrator to also charge for free listings. Administrator can set how much to charge. The expiration date feature should also apply to free listings.
