Add social profiles to a pet clothing website

I just need a simple social profile section implemented into this pet clothing website. It can use whatever simple method you think is best as long as it has an easy to access database for storing all of the clients login info. You can design the profile page how you want as long as it matches the rest of the site and includes the info below. Remember this is to be as simple as possible. 1. On the "Pawfile" tab create a login/register page that will lead to a sign up page or their personal pet profile if their already registered. At the top of this page also put a "Pawfile Search" bar so people can search through the other created profiles and save them as their friends. The sign up page only needs to collect their first and last name and email address to register. 2. For their profiles it would include a section for breed, age, favorite snack, pet nickname and a bio section as well as the option to upload up to 4 pictures with captions. At the bottom of their profile or wherever it looks best add a friends-list for them so they can save other peoples profiles.
