How to add More days

Dear Friend,

I like to know , how to add 4 different dates on the event and remove event start and the end dates.

As example :

we do have 3 or 4 different dates and time for a one event.

Event date 1:
08-1-2013 12:00 PM
Event date 2:
08-8-2013 13:00 PM
Event date 3:
08-16-2013 14:00 PM
Event date 4:
08-21-2013 15:00 PM

Please let me know soon as possible, if some one like to develop or do the modification to me, please let me know to discuss about payment .

Best Regards
