in progress : pdf pocket tank pattern

As I mentioned in an earlier post, I'm working on creating a downloadable pdf pattern and I've decided to test this out with the pocket tank I made this summer.  I've graded the pattern up
, written and illustrated all of the instructions and now just need to scan this pattern, digitize it up and turn it into a pdf download.  I'm pretty pumped up about how it's been going so far since this technical stuff is one of my fav parts of the design/creation process, guess that's why I freelance as a patternmaker, duh!  I think the hardest part is going to be trying to figure out how to offer something for download on this site.  If anyone has experience or suggestions I would love love to hear them, I've done a bit of  googsin'* and am not really coming up with the answer.
