E-ticket creator for websites

I need to add an e-ticket generator to some websites. I need this program written in a way that it can be added to regular wordpress websites. The program: -the admin can create a new event for which tickets are needed. The system will automatically put the tickets for sale on the front end on the day ticket sales are scheduled to go live -unique e-tickets are generated for the event with a specific color ticket for the event as well as a unique number for each ticket -the e-ticket is automatically emailed to the client -a daily. weekly monthly report of ticket sales is emailed to the admin -admin can view all sales records -a unique event logo may be added to the event tickets by the admin -a checkin system where employees of the event can login. They put in the confirmation number of the ticket to checkin guests and make sure people are not coming in with used tickets -admin can create employee access to the checkin module -admin can add other admin and allow various permissions ------- I would also be interested in a system that generates a unique QR code for each ticket. The other part of the system is a employee program where they scan the code with their phone to be sure the ticket has never been used and record attendance etc automatically
