Wordpress checkup

I need someone to do the following.

- check that my Wordpress website is secure and that it’s safe to browse on.
- check the speed of the website interns of browsing
- make sure when searched it shows correct subcategories. (It was showing prices of tours before but we do not do tours yet, we do have pages that will be used eventually for sales but at the moment they are not operational)

It’s basically just a check up so I know it’s secure and runs properly, from an outside user.

Any help would be great
