Joomla Order processing application

Hi, I need an application built for order processing for a small business. The application will be a joomla based application and will have various areas: - user management. this will take care of defining user groups (e.g. graphic designer, office manager, clerk, supervisor etc) and their corresponding privileges. (the privileges should be data driven e.g. the clerk can see orders but cannot modify them, the graphic designer can add a client but cannot delete a client). - client management. various forms to add/edit/delete clients. - order management. add/edit/delete order. associate orders with certain clients. copy orders for convenience when you create a new one etc. - inventory management. add/edit/delete inventory items/products. the inventory needs to dynamically connect to order processing. Please keep in mind that whatever is needed is going to be provided (e.g JUGA for user groups and acls, ChronoForms or RSForms for form processing etc). Of course everything is going to be database driven (exception is the media files/images that will be stored in the file system). I will help with details when it comes to the creation of the needed database [login to view URL] product needs to come with the documentation and installation instructions. If you need a more detailed description let me know via PM. Estimated time is 30 days plus/minus. Please if you bid make sure that you are available for this job. thanks
