here's how you promote it: focus on a very narrow market first because your current market is very broad and hard to attack. come up with one specific use case for this bad boy like invoices, and then narrow it even further, custom invoices for paypal, and then you have a tangible market you can start to attack, not an abstract one. my examples aren't probably the best, but you get the idea. excited for you!

the thing is to get some experience and momentum in getting a customer, which is very different than engineering code. lots of good will come out of it, and it will take you in directions you can't anticipate or imagine.

Agreed. Solid idea. Well executed. Demand Exists. But you need to narrow scope, at least initially. It would be very difficult to just focus on "invoices." Going up against some strong SEO competition there. Like jwheeler79 suggests, focusing on a very narrow market segment may be easier to gain some traction. There a tons of small sellers on Amazon, Ebay, etc., that may have very specific document needs that are not being met. They are probably using clunky, unprofessional solutions or trying to do it themselves. Find out what those needs are and very specifically market to them.
