Zarafa Modul for vTiger

I need someone that create an Modul for vTiger OpenSource CRM that implements the OpenSource Groupware Server Zarafa. All Functions of Zarafa had to be implemented: -Email -Contacts -Tasks -Calendar Also we need to add the customer details to the zarafa calendar and contacts. Needed Features: Installation: -It must be able to install this Module with the “Module Installation Manager” from vTiger. Configuration: -You have to be login with the following Zarafa variables: Username, Password and Server address (Hostname or IP) -It would be also nice (but it is not necessary) that you can configure this Information’s directly in the vTiger User Account. Functionality: -Access to your own Calendar, Tasks, Contacts, Inbox (with subfolders) and Notes. -Access to others shared Calendar, Tasks, Contacts, Inbox (with subfolders) and Notes. -Set the share permissions for Calendar, Tasks, Contacts, Inbox (with subfolders) and Notes directly in vTiger -Create, Edit and Delete Functions for Calendar, Tasks, Contacts, Inbox (with subfolders) and Notes. -Create Calendar Entries directly for the user and add automatically his contact information’s and addresses in the entries. -Create Calendar, Tasks, Contacts, Inbox (with subfolders) and Notes Entries for other Users, included the share permissions. -All the entries have to be on the zarafa server for sync with z-push. (Active Sync for smart phones. This works already, but the dates must be saved on the Zarafa Server for that!) -Sync vTiger with the Zarafa Contacts (must be able to set the contact group for sync.) -All functions must be fully integrated in vTiger like the existing calendar system. But with the design and functions from Zarafa. Best Regards
