1. Did you follow up your letters?
2. Do you know anything about writing copy? (If your letters start with 'Hi, my name is _ from _ and I do _', you're already lost)
Without having the answers to the foregoing questions, I'd suggest that you call the guys you wrote to. Atleast, they've heard of you. So it's not a 'cold' call at all. It makes things way more easy. And you got something you can relate to when you call, what saves the work of finding a catchy 'reason why to stay on the telephone'. (The key to $$$ in telemarketing.)
Secoundly, if there wasn't any response from your letter, that's a definite sign that your copy sucks. (No hurt feelings bro, if you want to improve you have to face your weaknesses.) I'd suggest that you study how master copywriters a) open a sale and b) close a sale. In fact, you could simply take a salesletter that pulled in millions and change it in terms of your needs & your offer. Names to search for in this regard are: Gary Bencivenga, Gary Halbert, Eugene Schwartz. (It might take some time to master selling in print, but every moment you'll put into it will pay off in a huge way.)
What I said in two sentences: Approach the prospects you wrote to more than once, because no woman will mary you right away after the first time she met you, metaphorically. And more important, learn how to approach the chick like a master does it, individually, unique and in way that seems special, not with lines all of them have heard umpteen times, like: 'Did it hurt?' 'Did what hurt?' 'When you fall from heaven...', or in our case: Hi my name is _, I do _...
People sort their mail next to the waste basket. They make an A and B pile. A is everything that seems important and looks personal. B is everything that is obviously advertising. The B pile goes directly to the basket. (Just watch it in places where people get a lot of mail, it's like a unsiversal law.) Even if you managed to get into the A pile, at the smallest sign of 'ADVERTISING!' (Flyers, Coupons etc. in the envelope) you'll land in that basket. Hide that you're selling as best as you can and even better: Make your advertising itself too valueable to toss away, and you'll see huge improvements in terms of conversions. (Gary Halbert used to stuff the orderform etc. in a 2nd envelope within the envelope, on which was written: 'Open after you've read the letter', just to bypass the 'Aw crap, advertising again'-effect.)
Nuf said, hope that makes any sense at all. Keep pushing forward. If you're persistant, you'll crack the code you need to make your system work.
