Any wedding theme templates recommendations? we need help..

hi friends =)  does anyone know how to buy and load a template site?  It must have a wedding theme where background images and icons are applicable for two people about to be married.  We have no idea how to make changes, as in we have limited technology experiences.  Earlier today we found something that could possibly work on rsvpwed.com so we have a solution.  But... maybe someone here knows of another one so we can made an educated decision on what to choose.  Always prefer free options, but since this date is special, we also have a small budget we can allocate for such a service.  God Bless - Laquita
