When your content is as good as you say, it would be easy to create a product (ebook) from this. If it is not enough for a book, make it a special report. 5 to 10 pages of really good information, nicely formated and having some pics or diagrams in it may be enough. Just think about someone who researches a certain health condition and then finds an informative report that summarizes in a few pages what he otherwise would have to dig out from several webpages.
Make pricing so that it is easy to buy. Put buyers on a mailing list so you can contact them with updated information or presell related products.

An other option I came across recently is using paypal for donations. Combining that with something like an Y!Answers style 'Ask the Expert' category might also work (but this needs constant monitoring and answering => work).

Good luck and keep us posted on how things turn out for oyu.
