OpenERP Installation, Configuration, Customization, Training, and Support

I need to install and configure OpenERP including the accounting & finance, HR, purchases, payrolls, project management, fleet management, warehouse, and analytic accounts modules. \r\n\r\nAlso, I need some customization to the modules like payrolls, project management, purchases, ... to match my needs. Example: Modify the payroll to be entered daily, and to be able to link an employee to a project or more. To customize the project cost calculation to be related to the consumed items instead of the purchased material costs. Other customization requests similar to this are also applied.\r\n\r\nThen, I need to be trained me and my employees to use the system and administer it as well.
