Beagle bone Black RS485 Project

I have a BeagleBone Black with 7" TFT / Touchscreen Cape. I am looking for someone to write me a custom application. It will send a command out on a local RS485 network to receive information for several local devices, each will reply with a status timer. This will then be displayed locally on the TFT with some nice icons, etc. Showing status, and customer logo, site name, date and time etc. It will also send this stats upto an SQL server that is internet facing. Must have a configuration page, and on screen setup, to enter the following. Site name, number of local RS485 devices to scan, scanning interval, Ethernet setup(DHCP and Static), SQL server and port. This should only be accessed via a username as password. We should be able to show device errors on the screen also, e.g. no internet connection, RS485 device in error, or offline etc. I will provide the protocol document for the RS485 devices. I have hardware here ready for testing.
