1) What's been your cost per customer? Maybe it's your expectations that are incorrect. That said from what I'll say below I doubt this.

2) Your website isn't appealing to sign-up to. Lack of information, or anything really. You need to rethink your landing experiences I cant see very good conversion happening.

3) You ask for a heap of personal information without establishing any trust - see above. Having a Gmail address as you contact really exacerbates that this is not a serious/legitimate business.

4) I feel this post is veiled attempt to bring exposure. I've offered some advice in the hope that im wrong.

5) I cant see this business working as is. But good luck.
