SMS Marketing: How can I do better?

Ok just a quick run down, so far I've setup a corporation for marketing, created merchant accounts, scraped yellow pages and got a nice sales call app from android to call businesses on the fly without dialing so I can call 2-300 businesses a day. I used the well known phone and email script from Areevez, I'm able to get past gate keepers and follow up fairly well. I've passed out a good amount of business cards, had appointments with business owners, had them tell me how much potential they think this has etc. Yet for some reason or another I can't get it to materialize in sales.

Once I finish talking to them in our appointments I tell em ok let's start setting this up for you but they tell me they have to run it through their partner, or through corporate etc and I don't hear from them again. I follow up but the interest disappears. It's been about a month and still no sales. I'm even offering a month free just so they can taste it, get their clients on board and start seeing its effectiveness. But regardless it just doesn't get them to call/email me back.

I'm not about whining, I'm running into a brick wall and I want to know how to get around it.
