Make current site with MySQL/PHP = pretty with CSS and Ajax

I have a PHP site that has a MySQL database already. What I want is somebody to come in and do some custom Ajax/JS/CSS that makes the site pretty and function slightly different. This person may need to know MySQL as well if there is something they need to change to make the interface work the way it should. This site is so we can track clients and see history quickly from anywhere in the world. Search for a client in the database and see the history from each tech. **Current Working functions are:** -Sing up your company (whoever signs up the company is "admin" over the employees) -Add employees -Then the admin or employees can add clients and collaborate on them. -post notes about clients and it shows who posted that note, and a date for that note. -Every company is separate from other people creating companies. **Things needed to be done:** **(look and feel mainly)** *Uploading/Adding clients should be easy *Searching for a client should be easy *Adding a note quickly should be simple *Watching the latest posts or "notes" should be fluid * I want the site to be able to import CSV, XLS customer data. Company name, name, phone#, address, email. *Take a look at the images attached. This is actually quite simple and a small project. It just sounds like a lot. *(everything in **RED** is only on the image for explanation) Attached images show basics of how the site works in a browser. **Sites that have existing components I'd like: (cosmetic)** I like this basic sign in page [login to view URL] This next page works the way I'd like the spot next to "search" to work. [login to view URL] Bringing up the latest "posts/notes" in a live view on the search page as shown in my image attached. Notice on this next page when you click on the features - how they open up [login to view URL] This is about how I'd like the "notes/posts" to be after a search is done. Seeing the drop down of the history of notes, but being able to expand them like this. Before they are expanded, you could see the date and posters name.
