One of my customers wants to create a website to advertise their service (a recreational service, 4 wheel driving in Queenstown), including showing videos. It should allow them to book and pay online, using a credit card. I guess an NZ based service would be better, as it would allow integration with local credit card processors, but I imagine a significant fraction of the users would be from overseas.

Does anyone have any suggestions for the best way to achieve this? Either a hosted service that runs everything, or some kind of extension to Wordpress that allows it to happen? Payment will need to be done using a third party service, my customer doesn't want to mess with credit cards themselves.

For example Booking Bug is one option, but it's US based.
