Booking

Hi,
I am building a website for cars, equipment and hall owners to advertise their goods for rental and where customers can book/hire them directly from my site. Which means owners will be able to upload their goods via front end. Once uploaded it will have its own calendar booking option. This will be managed by the owner.

As such I am looking for a theme or plug-in that can support the following features. Is there a plug-in/theme can support please let me know and possibly send me a link to a demo admin and front-end.

Features looking for,
Front-end posting/upload
Calendar for each good (car, hall, equipment)
Owner managing calendar

Thanks
