Bex,
Perhaps you might consider an incremental approach.
The major problem will be the conservative mindset of your potential buyers. They won't buy it just because it's GOOD. Such expenditures by individuals will always be heavily tainted by emotions.
Marketing will be a major expense, to Change their minds.
It may work better if you first prove your unconventional (I mean that in a positive sense) aircraft with a conventional motor, then after it is seen to be practical and 'cool' and practical, move to step two and market the electric powered version.
Although mass marketing has convinced most of the world that Coca version of Cola is not only cool, but worth paying extra for, I suspect that their marketing budget is VERY generous.
It would take such a massive marketing plan to get pilots to part with their cash to risk buying an unconventional (and some will call it strange just because it's different) aircraft powered by a radical motor (that's how their wife will see it)
I'm all in favor of your ambition
