I think it's a good idea, at the very least worth a try. If nobody comes, you haven't lost anything. If they do come, you get to know your customers.
I'm on the other side of the world, so I don't exactly have any views on how this goes in Canada, but did you do some market research ? How many people actually require this service ? Or businesses ? Have you checked other sites such as
http://www.scanmyphotos.com for example on how they do this and their prices ? Are you competitive to them ? If not, can you offer other advantages ?
Make certain to use the right keywords : when I look at Google trends, you can see that certain words are much higher than others :

I repeat I don't know anything about this business, but my first impression is that this is a niche business. Not everybody needs this. Unless you are very well known, this does not seem something that will immediately generate you steady income.
Don't just depend on your website to make yourself known. Try walking into some local businesses and explain to them what you offer. Show them the advantages of digitizing their receipts / old documents. Drop some flyers in shops around town(s) advertising your shop.
Your website : it's definitely better, but it's still not what I would charitably call "good enough". Keep working on it though, it's already much more logical.
