Hi,
I have been gone through your requirements. Basically you want to an admin side where admin can add update and delete entries in portfolio. And there will be a page on front side where only logged in users will have access to view that portfolio.
I can do this task very efficiently. I can also make your design better using bootstrap ( HTML Design framework) so that your site will be responsive. Please chek out www.paincure.co.in.
This site also has gallery which is maintained from admin side. This site also works on tablets and mobile phones.
I am new to freelancer. But you can give me a chance. Release money when you get satisfied.
