OK I have leads... now what?

Hello all... yeah I'm a noob so please take it easy on me

I've been in this "home business" for about a month now, and I have "captured" a list of appx 200 people. I have actually gotten 30 or so people to sign up for the "free trial", and I've gotten 1 guy to "buy in" to this system that I'm marketing.

I've been sending emails to my leads maybe once or twice a week... trying to advertise the benefits to becoming a paid member.

I've even gone so far as "rebating" $100 once they sign up (I have a great-paying fulltime job so the $100 will not be missed), and I offer to create their website and offer web marketing tips... I can't get these folks to sign up.

I sent out an "opt-out" email to give them a "way out" of my emails in case I was aggrevating them, but only a few people actually opted out. Maybe they've "spammed" my email address... I have no idea.

So my question is... what else can I do to entice people to become paid members? Are there any "tricks" that you guys have used to get folks to buy a service or product?

Just trying to get advice from the pros. Any advice would be much appreciated.

Thanks all,

Droopy
