Wordpress site updated - Google search results optimised

I'm in need of some web design updates. The taxi company I'm a director of currently has a very basic wordpress website, which is working OK, but we need some updates. https://armidaletaxis.com.au/

The site was designed by someone using a template. On occassion some of the template (it seems to be a rental car template for wordpress used by previous designer) is displaying on google (it's all latin etc). We need all of this removed and tidied up please.

We also use the website for customers to book taxis directly using some json plugin https://armidaletaxis.com.au/plugin/config.json provided by our dispatch system. I belive this generates a dialogue box on the main page. I'd like to create an eaiser, more direct way for passengers to book direclty off google.

We have over 2500 people per month search for "Armidle Taxis" using Google, they then press the "call" button which displays from the google "places" or "my business". I would like for the first thing a customer sees to be a "Book Now" button they can click to take them to a clean - mobile friendly page using the JSON plugin, so within a few seconds they can enter a name, phone number, pickup address and book a taxi...

Is this something your team can help with?

Thankyou!
