Marketing, design and branding expert here… I took a look at the site.
You have a lot of work to do.
- 
the domain is terrible. You won’t see any traction with a domain like that. 
- 
your branding is non existent. 
- 
your messaging is non existent 
- 
the UI is confusing and doesn’t follow any standards at all. 
I understand you’re looking for advice, but all I see is a basic mock-up that doesn’t make much sense.
If you’re a dev, I think you need a designer on your team more than a marketer at this stage.
