Database with reports PHP/MySQL

The database is for a costumer, who wants to collect information about quarterly updates of geographic data. The database allready exists in a first version, which I did with PHPMaker. But this programming is not object oriented and the costumer needs some additional features. So I would like to do the complete database new, based on the existing database structure and logic. So this project includes: - Re-Programming of the old database application (again with passwort security, simple user right management, export to excel, search function, filter refining, but object oriented) - Programming of some reports (e.g. differences between the data of choosen quarters, counting of results, simple statistics etc.) - expansion of the database with additional kinds of data, which have to be linked to the existing entries. I know, it is very heavy to bid on this description, but I can not describe every detail here. Please bid the maximum price for such a project and later we qualify the price when you exactly know everything about the work to do. German speakers prefered.
