Build Web Page (Similar to Google Analytics)

We need to build a web page (similar to Google Analytics). The requeriments are: - Login (for clients and administrators), password recovery, etc. - Administration page (Create new clients; choose an specific logo for each client; select the charts, indicators and tables that the client will see) - Similar options as Google Analytics (choose dates for the charts, indicators, tables, etc). We are currently working on all the charts and indicators that we're going to add to the page, you will have to add this information as we generate it, but the limit is 20 charts, 20 indicators and 20 tables for the base payment and we're going to pay extra for every additional chart, indicator or table. - You can use open flash charts to build the charts, so you don't have to create a library for the charts. - You can base the design in google analytics, so you don't have to create the design yourself. - We will provide the data for the charts, indicators and tables. You have to consider further modifications to the requirements, as long as they don't present a major change.
