I need a new website to advertise my services on the internet and google.

The website need to have the same concept of purecarmechanics.co.uk and is to look good on mobile too. I need to include some social media together with some proper SEO to rank on google for some specific keywords.

I don't really mind what type of system to be used as long as it's easy to use for me and has all my requirements.

Thanks.
