Need to connect an LCD wirlessly

I need to connect two LCD's at my work place

1.via VGA cable

2.wirelss (so that there is only need to connect a power cord)

I found a Samsung latest LCD ldx190s but not available yet in the market and expected cost is around $500 to $600

have any other idea rather cheap at least available. and its better be compact so that i have to move the wireless one frequently(within the wireless signal range)
