Resolve Snags After Website Upload

Snags after Website Upload Background: I have a website on which two separate development projects were recently completed and uploaded. The first team of developers uploaded their project. The work was tested and the user interface and the admin panel worked fine. A couple of weeks later the second team of developers uploaded their project work. It also was tested and both the user interface for their section and the admin panel worked fine. Unfortunately, after the upload of the second project faults have appeared in the user interface and admin panel for the first project. Requirement: I am seeking a developer or team who can find, diagnose and rectify the faults which have appeared and resolve these issues within one week. The total number of charts in the suite is 15 main charts and a number of subsidiary charts. Charts with faults and the type and number of faults are listed below: A. Fusion Charts Fault: Tool tip data not displaying - 1 chart affected for both Users and Moderators B. PHP Fault: Chart wrongly positioned on page with or without PHP Error warning message - 4 charts affected for both User and Moderator C. MySQL Faults: 1. Data in data base but chart not displayed - 2 moderator and user charts 2. Charts displaying wrong horizontal axis categories and data not mapped correctly in Admin interface - 4 charts affected for both User and Moderator Note: In most cases he errors effect the same charts for both User and Moderator. Developer Information: The user interface consists of two sets of business information charts. The charts can be accessed by users with two levels of permissions: standard users can view the charts for their own geographical area only. Moderators can view all geographical areas and view the charts side by side – they can compare one location with another. Please see attached a brief with description of the faults that have appeared in charts for the User and Moderators and in the Admin Panel. The site is based on Codeigniter and Fusion Charts. Financial: there will only be one Milestone payment. It will be made at the end of the project when the task has been completed, the new code uploaded and tested on the operational site.
