Which theme for a (my!) wedding ... and maybe some plugin

Hi everyone!
I'm gonna get married :smiley:
So, i'm a begginer on wordpress even if i created a website for my small business (some of you helped me to do that... thank you!)
I'd like to build a nice and simple website for my wedding.
An example of what i want: http://goo.gl/ncMhnE

I searched for a "parallax" theme but on there free version, it's not good.

Is there any WMPU Theme that could help me to do this easily? And maybe also plugins (like the "RSVP" one at the end of the pages)

Thanks a lot!
