Step 1: Install Wordpress. Good, already done.
Step 2: Create a big ol' list of keywords which you think are relevant to your business. For example, [sign contract online], [sign document online], [sign contract with iPhone], [sign contract with Blackberry], etc etc. This doesn't cost anything more than your time.
Step 3: Design a template which, given a particular keyword, includes a few hundred words of content about the keyword and also acts as a landing page for your service. I'm assuming this is effectively free for most of us on HN. The last time I did it it required copy/pasting one file in Wordpress and then five minutes of hacking the PHP to do what I wanted it to do.
Step 4: Write between 50 and 100 of these, depending on how you get them done. This is what costs the $1,000, since you're probably going to zone out after doing this five times, write up the process, and then hire the rest out to freelancers.
Predicted results: on average, depending on query volumes, you're going to pick up a handful of hits for each page every month for life. So instead of having 1,400 clicks once, you'll get somewhere on the order of 400 clicks a month for forever. And instead of them being someone who was just gawking at a pretty girl in Chemistry class or poking their sheep while farming virtual cabbage, it will be someone who is right now trying to solve a problem which is costing their business money.
And if you have $2,000 to spend? It scales right on up.
And if you're savvy about how you do this? Suffice it to say that the MVP of this project gets you a wee little asset to build a business on, and implementing this strategy in a really effective way can basically carry a business on it's back. This is not limited to bingo card publishing empires, trust me.
