As thisguy points out, the guitar in your pic is a Music Zoo Natural Series with a Koa body. The Natural Series guitars come up for sale all the time for great prices, but the Koa bodies are more rare and come up for sale way less often, although I did see one recently - was a single pickup, v-trem guitar though and the price was sky high...
IMO, the closest you are going to get for a reasonable price is to wait for a mahogany body Natural Series to come up - you should be able to score one of those for $1100-1300. It's going to be tough to find one with a neck single coil though. Another option would be to get the exact parts you want from Musikraft and build it yourself, but, no way you are getting Koa from them. You could get a Mahogany body from them laid out exactly like you want though and they have the best "Charvel style" parts from any of the major body/neck suppliers IMO...
