A more professional landing page would make you seem more legitimate, yes. This looks very sketchy. I'm not saying you're running a scam; I can see this being a real and valid service, especially in Silicon Valley where startups are created to cater to other startups. But your site looks like a high school web design class mockup.

I'm not trying to be rude, just honest criticism. I wouldn't trust you based on that site. At a minimum, ditch the "sexy" stock photo of the woman pumping gas and the "time is money" graphic, find some real testimonials (you don't even have to have headshots; screenshot some positive Twitter feedback and use that, with permission of the authors of course). Definitely talk about the insurance policy, and give a little more detail about the service without being too wordy.

It's more that a bad landing page demolishes potential trust.

Especially fake testimonials. https://omnibox.tv/ has your same "Ben A." as "Gerald Perkins". http://www.shopkare.com/ has "Rachele B." as "Ana Lopez". All it takes is a right-click menu in Chrome to figure out it's a lie.

People respond to a lot of subtle signals.

* You don't have a shortcode to text to, so it feels like you are texting to some dude.

* For such a local service, you don't say what area the service works in.

* Not using your domain for email.
