Need to create a e-invitation website focusing mainly on wedding but also will have other invitation like b-party,housewarming....etc as optional.

looking for something like http://www.pingg.com

below is my requirements

The reason why I wanted to have format similar to pingg.com is to have single page invitation creation format with ajax enabled thus making user-friendly page for any kind of user.

also the main category will be for wedding invitations.

other category includes baby-kids,Custom e-cards,holidays,birthday,Anniversary-Invitations,House-Warming-Cards,Engagement-Party-Invitations,

Under wedding category I wanted to highlight Indian wedding cards more along with other country and religious wedding cards .

Hindu cards will have more categories.

In general the theme should be pleasant and appealing to users also should resemble social media portal.
Also the theme and layout should express heritage and cultural touch but not specific to any religion .

The form and css design of the site should be looking like social media portal. For example the the user registration forms or any form should appear as twitter registration forms.

The business and marketing ideas of pingg.com should be imported to this site also.

clear and easy admin panel to manage the site.
