Service Industry for Invoicing, Purchase Orders and Sales Orders

We run a service business, we would like to be able to link multiple contacts (which we would service) to the purchase order and in turn send that to our employees as their services for the week (thus we would need multiple linking days for the calendar), in turn some would require multiple employees to work on the one job, however we do not want to make all scheduled jobs of all employees public for privacy issues.
