I went through your website and I can see so many improvements.

Firstly, I can't quite understand what your website does when I get on it. I would still be confused if you wouldn't have explained it yourself above. That is bad.

I'd suggest you start with making your website copy a lot better. A good copy goes a long way. Good copy can get your users/visitors to do what you want which is sign up for an account in this case.

After the copy comes the User Experience and User Interface. I see a lot of improvements small and big that can increase your conversion rate. Here's a hint, your Sign Up button is not so prevalent on the homepage. It could be improved. Using just plain Sign Up is not as effective as it could be when accompanied by a handful of the most important reasons for why they should Sign Up.

Your layout looks cluttered at the moment. It could use white space. Cleaning it up and setting it up more like a landing page then a listing page can be a lot more effective. You can effectively tell your visitors/users what to do in that way.

I have a lot more suggestions in mind that could make your website/process very effective. I'd be happy to discuss them in detail through a call.
