I can get wood like this and other designs from our local hardware store.
Any Niteshade amplifier can be integrated. There are choices as well: Passive or active. Active means there will be a tube amplification stage before the amplifier's input. Passive does not increase the front end gain. (I can talk more about this.)
I can install a remote in an amplifier or preamplifier.
Yes, I can make 220V compatible amplifiers.
