With over 10 years experience with PHP and MySQL, I can develop the business management project. I also develop with HTML, CSS, JavaScript, AJAX, jQuery and the CodeIgniter framework. I have recently been developing a custom modular CMS that would be perfect for this project.
The CMS includes several core modules that can be extended to fit your project needs such as Members, Groups, Permissions, Pages, Themes, Settings, Files and much more. With the CMS being modular, it allows for each feature to be self-contained within it's own directory as well as its own logic. This allows for features to be added or existing modules to be modified without shutting down the entire system.
After reviewing the 3 attachments, I believe with my CMS that it can be completed within 30 days and look good with some ajax features. If you would like to see a demo of my CMS, please let me know and I will get a demo up for you to play around with.
I am the type of developer that likes to throw out ideas to make projects better. I usually work 10 hours a day and will work weekends to meet deadlines. I report to my clients frequently so they are not in the dark on whats going on.
If you have any questions, please feel free to ask. Thank you for your time and good luck with your project.
