I suck at getting traffic!!! Help!!

I can research markets, write sales letters, products, do graphics myself, build websites, figure out the code to protect downloads, add payment buttons, pop ups, and everything else involved in selling infoproducts except....get traffic! I seem to be stuck at getting traffic and I'm hurting for real methods, here. So when it comes to testing my sales letters for conversion rates before opening them up to affiliates, I'm at a loss.

PPC - expensive, but I suppose the best way to get targeted traffic for testing purposes....??? But then if I have pop-ups that re-direct to a trial offer, I can't use at least Google PPC. So I can't ever test the real sales page to see if it works using this method.

Article marketing - since Farmer, as far as mass submissions to article directories go, is now apparently very weak and no help to SEO either because of diluted PR

Building a niche site - takes years, and my two experiences with it have been lackluster at best - two niche sites get OK traffic, but this took YEARS to develop and HUNDREDS of articles written - I need to test conversion rates for this sales letter and place it in the CB Marketplace, not write a hundred more articles and wait a year for Google to rank it and then HOPE it ranks it in the right keyword range.

Guest posting - seems like a good method, but then direct the traffic....where? Not to a sales page. The site owner ain't gonna like a guest post if it is just a pre-pitch for a product. So direct the traffic to a niche site then? And then what? Have to build a whole niche site just to test a sales letter? Here we go again. Seems like more product creation when I already have a product.

What else is there? All these methods seem lackluster at best. I have dozens of ebooks on internet marketing, and they are all very good at describing product research, creation, etc, and then they all end with "Oh, you now, now all you have to do is send traffic to it!"

Any suggestions, here?
