Make a web site.
blog about it
get a paypal account
there were sites that used to do things like this but I think they are mostly passe now. (cnet and others)
Go to forums or sites that relate to the product/software. Introduce it - but not in offensive or underhanded ways. Participate in forums or discussions/become one of the "experts" if that is relevant to the domain.
Make a video or a podcast about it and put it out there. youtube, etc.
Show how to use it in the video or podcast.
Hosting is CHEAP. Paypal setup is free. Try it out. You have nothing to lose. It is not going to be an overnight thing. It will take time. If it doesn't work, at least you have the experience for the next one.
EDIT:
ChrisW's advice/post is good.
Here is an excerpt from one of the links within his link:

In my personal experience, getting that first $1,000 a month was mostly about getting the product and website polished. The second $1,000 for me was about 50-50 improved use of AdWords and creative SEO. (Apparently there are a couple hundred people out there who really, really need Insect Bingo cards. Some portion are willing to pay. Repeat times a few hundred.)
After you've doubled once to $2,000, you know all you need to do to get $10,000? Repeat the $1k to $2k process about 2 times and then add a little to push you over the finish line. (I'm not mentally invested in ever seeing $10k a month with BCC, but I have absolutely no doubt I'll hit $3k and probably $4k eventually. So much in this business scales geometrically rather than arithmatically, which is good news for us -- the difficulty of multiplying by 2 doesn't vary wildly.)
