Derek, for the price hes charging you could add a couple of sites. The beauty of these is you can alter the wording any time you like. If you have special offers at different times of the year you can put them in, no problem.
I really think that any carpet cleaner that doesnt take Mark up on this offer is losing out.
I have also had my other site SEO`d by Kev Loomes and it is performing much better now, so anyone looking at going down that road, Kev does a great job as well.
