Well, I figure the cheapest you could hire an engineer of that skill would be around $50 US/hour. Just the soldering time alone would cost $1000. Add in 10 months of development time at the same rates, and you're looking at $20,000 if he's only working on it 10 hours a week. If you're lucky enough to hire him at a cheaper rate (say half that), you're still looking at a minimum of over $10,000 US.

All I know is that if I had that kind of expendable cash, I probably wouldn't be spending it on a remote Empeg display...
