Motorola SLVR L7c

I work for a sprint 3rd party store in the affiliate market. I'm due for an upgrade and am wanting the slvr, mostly because i don't like flip phones. Due to the exclusive Best Buy has i tried to upgrade there, but was not able to complete it, CS said since i'm on an employee plan i need to go through my rep. But we don't have that available. Does anybody know a way to make something work to upgrade to the slvr?
