To get early customers I like the domino theory that Clayton Christensen first described in his book Crossing the Chasm (assuming you have built a product that solves an actual, difficult to solve customer problem that is worth paying for):
1. Start with one (paying customer), that customer then;
2. Gives a testimonial that you can use to sell other similar customers and;
3. Actually provides you names (and sometimes even actual referrals) of other customers you can sell to.
As you build reference customers it gets easier to sell to other customers because now you start to get a rep as a must have in that particular industry.
Nowhere in your posting do I see anything about "we have X number of customers" or "we worked with X number of customers when developing our product". If you spent $60k plus your own time developing a product before showing it to any customers it's possible that there is no need for the product, and that more than anything may be why you are not getting the response you want from either investors, "journalists" or customers.
I know how this can happen, I've been there myself! (It seemed like a good idea when we started building it, how come nobody wants to buy?)
