Raul,
That's pretty much what you'd pay for a decent rendering over here as well - though in all honesty the best feature renderings are usually watercolours which run about US $5000+. Computer renderings are usually used as the supplemental images.
I still have a fondness for the older style freehand coloured marker renderings as well. Though they do tend to rely a little too much on seagulls, sailboats and perversely gleeful families!
Though, the computer rendering guys seem to have a preference for Porsches and baywatch women...
Cheers
