currency, multiple databases

We want a solution created to display an amount from a file/DB; 1. The amounts will be in óne file or admin/DB. 2. The amounts will be displayed on different sites with different DBs. 3. you must create some sort of currency-convertor. 4. It must be possible to add treatments. 5. it must be possible to add currency. 6. It must be possible to change the rate for currencies. 7. the amounts under the currency-columns is automatically changed when a rate is changed. 8. currency-column is automtically, only rate is changed. 9. We need an easy solution on how to input amount(s) in a WYSIWYG-editor in Joomla admin. 10. it must be possible to show (example:) "treatment 5" with currency 2 on a Joomla-site, and easily input this "code" in the WYSIWYG-editor 11. It must be possible to show the amounts on regular php-sites 12. The data needs to be changed in a file, or an admin (not in the phpMySQL-enviroment). The amounts will be changed by someone with little knowledge of computer. We will give you access to an account with FTP, phpMySQL, and other webservices required. We will give you the standard and 3 currencies to work with. Look at attached file for an example of how it could look like. How would you go about for this project?
