Domestic Cleaning Gloucestershire – Review Needed

I was asked by a friend to put together a site for her new domestic cleaning business. Now I am not a web designer I simply dabble in my spare time. The site I have put together is NOT a template it is XHTML and CSS I have put together myself.

Briody Hartwell – Domestic Cleaning Gloucestershire

When making the site I have done included the following:

– Simple URL Structure
– SEO Friendly Pages (to the best of my limited knowledge)
– Fast Loading Pages
– Simple Naigation
– Supplied as much info on the site as possible
– Includes Google Analytics
– Submitted sitemap to Google Webmaster Tools
– Site is XHTML and CSS Valid
SEMrush

I am looking for any help, problems or suggestions for the site which you think will make it better.

As I said above I am not a web designer so but gentle, but at the same time all comments and suggestions welcome.
