okay i got a real idea you might want to look into-
motorbike engines for using in kit cars are big business in the uk, 1litre and up superbikes, the engines go for £2000 and up ($4000) for something like a hayabusa, and in the us (dont know about canada) they are a hell of a lot cheaper, from bikes that have been crashed (pretty inevitable with superbikes)- i saw some on US ebay well under half that price. my idea would be to get a shipping container and fill it with engines (or part fill it whatever), ship it over to the uk and sell them on ebay. at the moment demand is massively outstripping supply, and people are throwing their money at these engines. there would obviously be a lot of matters to look into, but you could easily fit 25 engines in a container, which could be about $40000 profit.
its something im gonna look into when i have the time, there are obviously big floors in the idea, but they could be smoothed over.
