Fix Google Not Displaying Info About Website

I need a person who has lots of gigs completed successfully, to do a simple bug fix for my Google site.

When the address is put into Google search the website name comes up but the line telling you about what the site does not show, the search says 'no information is available for this page'.

I would like someone to correct this so the details of the page are visible on Google under the names of the business. (it may possibly be to do with robots.text?)
