I would take a look at what other people are charging for eBooks in the same industry, and then just try testing a few different price points. There a quite a few ebooks for sale on eBay and Craigslist, so that could be a good place to start.
As for length, I would say least 40 pages to make it worth the money, and up to about 60-80 pages. You can pad it out a bit with graphics and formatting.
This isn't really our area of expertise, but I hope that provides some help :)
