Build my web application PHP/DB/AJAX/CSS

Project Budget (USD)
$500 - $1250

Project Description:
I need help with a web application. It is run on a web hotel and should use PHP/MySql or PostgreSQL. The application is about 15 pages/about 10 tables. The site has a front end that generates texts, and a back-end.

I want at least one page to use AJAX. AJAX could be useful in other places and can be used more if agreed upon. I require basic but presentable design in CSS; white background, a place for my logo, appropriate CSS selectors, sans serif. I welcome your suggestions to improve any part of the web application. The application need be able to handle dozens of concurrent users on the front end, and to download large data sets (thousands of rows) reasonably fast.

The site needs login and accounts/normal security (no sql injections), accept uploadable images, generate modified stylesheets, and generate data files for download into excel.

An impressive performance will lead to further jobs.

- Fixed price for entire site, payable 35%/65% on two milestones. I reserve the right to cancel the second part of the project/second milestone, if for example, I don’t feel we work well together.
