Resources for OCR and hosting could be provided by the users themselves. You doing it for them could be the expensive option that justifies getting the credit card out :)
Apple Notes of your note book, then Markdown “Exporter” app* into a static blog generator of choice does require that last thing, a statis blog generator, which may(?) be worth the $8/month of hassle alone.

Anecdotal, but i've never seen a coffee that expensive. A coffee machine in France is usually < 1€ (more like 50c), and i've never paid more than 1.5€ for in an actual café.
Back on topic, i agree with the sentiment that this is the kind of tool you wouldn't use for business and therefore wouldn't get your credit card for immediately. A free-software, donation-based model may attract more people and make more money (and make grumpy librists like me happy).

Second thing is there's no way to try it out. I don't really want to drop $99 on something without having any idea whether it's going to work for me, especially as handwriting recognition is so sketchy and I have no idea what it's going to be like.
