Since you are on a related field. How much do you think we must charge for specialization in reverse engineering, application virtualization, and windows drivers?
In my experience, dealing with US companies from abroad, it is difficult to sell at very high prices. It happens but my company cannot loose prospective customers if the price is lower but convenient.
Absolutely no less than $1600/day. If you're doing reversing work or special-case driver stuff (can't speak to virtualization, but I'd assume similar), at least $2000/day. This sort of work is very niche, which means that if you're established, you can bill quite high up.
I'm pretty sure if you just ask anyone who has ever contributed a driver to the Linux kernel you can find someone who is willing to do "revesing work or special-case driver stuff" for WAY less than $2000/day.
