You can export a separate style sheet from quark in the export options (its a tickable box in the bottom right of export). If you were to more copy on the front page that would deffinately help. I don't think you need to redesign it as it looks good. Also google loves titles and descriptions, so try and give each page a different title and description. e.g
say for the home page.
Hot sauce Creative design - Your One Stop Shop for all your Graphic Design and Printing needs (try and get where you are in there)
so put
Hot sauce Creative design - Your One Stop Shop for all your Graphic Design and Printing needs in and around Wigan,
Lancashire
and for description try and repeat a few of your key words that are in the title.
Hot sauce Creative design - Top quality, affordable graphic design and print in Wigan, Lankashire
on the second title and description google will see the word design X 4, Wigan and Lankashire X 2, Print X 2. Now if you apply this to all of your pages but focus on different keywords for each page, such as web design, leaflets and flyers, but awlays put Wigan Lankashire in there and then if someone puts in say Graphic design in wigan you have a better chance of it popping up.
Google can take from a week or two to index your site, up to 2 months, so its just a waiting game really.
Good luck, hope this makes sense.
