You could also use any of a range of free unlimited file sharing services. Just Google for "free upload" and browse the options. (Some require an account, others make a document expire after a set period of time or inactivity.) Then, simply post a link.
As the amount of text on a handwritten page is relatively small, have you considered typing an equivalent Word document? Using an appropriate "handwriting" font. (Perhaps only for some pages.) Or, make HTML directly. It would be searchable from the web. You could eventually expand web pages to include images. Many free tools are available.
