Changes in a web for a Funerary Services and little script

I have done a site for a funerary services company. Now I need to migrate de site in a new template, adapting the site correctly without mistakes. I will need to add a new page named: "obituary" where this info for visitors should be shown: Name, Surname, location and comments total: 4 fields as here: [login to view URL] This fields will be introduced by the admin of the site so it would be necessary to create a page specially for him with user and password to get into and add the rececent deceases.
