cisco packet tracer expert

Please read the following . I need a packet tracer file. that shows Client Requirements section Existing Network Setup The existing LAN at both the central distribution site and the remote warehouse consists of a bus topology using co-axial cabling to connect approximately 20 PCs. Each PC connects to local printers using peer-to-peer sharing and the central site currently connects to the remote warehouse 5 miles away using an ISDN line. They do not have the facility to back-up any of the data at the moment. Both sites have business broadband access for Internet, email etc. Client Requirements The company wish to upgrade and expand the number of PCs (initially to a total of 50) at both the central distribution site and the remote warehouse. They require a modern structured network that can easily grow to meet future demands. They also want to deploy large multi-function networked printers (to replace the peer-to-peer shared printers) and two servers that can be accessed from both sites. They also want to look at wireless technology, initially for the tracking of stock in the warehouse environment. The client has indicated they wish to have a means of backing up all the data to the servers and want both sites to be able to operate independently of each other should connectivity be lost between the two sites. The link between the two sites needs to be upgraded and some form of back-up link put in place for resilience should the main link fail.
