Small Admin Control (PHP)

Hi, I’m making a website for my friend. I can make whole site static but I want to give control of portfolio section from admin section so my friend can add/edit Project page for each category and content in projects pages. I can't work on PHP or Database i don't know how to make admin section so I want you to do it for me. Here are two files (.jpg) attached you can see. one is the Project category list main page ([login to view URL]) other is the project display page ([login to view URL]) for each category with small thumbnail images on top half page and when we click on thumbnail it'll show the large size image and information about that work. That page will be separate for each category. I can make Portfolio main page ([login to view URL]) simple in html. What to do from admin section? I want to create each category page from admin section and then add thumbnail images , large image for each thumbnail and information on right side. When we create a new page it generates the link so I can make category main page hyperlinked to that php page. One more thing. Look at “[login to view URL]” you can scroll thumbnails to right left. I need that script too. If this detail is not enough, let me know. Show me atleast your 2 past projects where client can make changes from admin section. Bidder with low price will win. You should have your server of show me the demo of admin section.
