Hard to price a novel bike like that, but my uneducated guess is you'd be lucky to get $1,000. It's unique, but it's still just an 'other than top name brand' road bike. I can't see the Mg frame being that much of a draw.
If there is a niche market for these, you'll probably need to cast a wide net to find it. Which may mean eBay if you're not in a major metro area. Good luck.
