Website Pages/Modules Converted to AJAX

I have about 6 pages on a website right now that organize and display data from my MySQL database using PHP. I would ideally like all of these queries to load through AJAX, populating the modules and pages with new data as it is posted to the database. I'd like the modules to display the last 10 entries, with left/right arrows at the bottom of the module to load the next 10 entries, or go back to the last 10. I'd like to have a loading indicator as well. The data that is displayed within these modules is defined by the account by which the data was created. So I have a bunch of data in my database table, and it is being displayed according to the current account session. I have a simple notification system that already works that alerts users of new data in particular groups.. It would be great to be able to have these notifications load automatically on the notification bar without having to reload the page. --- I also need a search feature for user listings on one of the pages. My users are categorized by different traits within different categories (4 categories, 5-10 traits in each) so I'd like the search feature to: 1) Have 4 search categories to choose from, and when a category is picked, prepare the query of volunteers with traits within that category. 2) As a user begins typing a trait into the search bar, in order to refine their search of users, the search bar provides auto-fill suggestions of all traits within that category. 3) Once a user has defined the category to search within, and the trait to identify the users by, load the 20 first users, and then have a button below the 20th user to load more users, with AJAX. 4) I'd also like an export function and button that allows a user to export (.xls .xlsx. .csv) all users or the users that have come up in their search. --- Time is of great importance for the project, I'd really like to have this project completed this week if possible. Please try to provide examples of past AJAX work with your bid. Thanks so much for you time!
