exactly it is well priced ! Considering what companies get as a result it is well worth it.
Like I said I called a major seo company in the UK to see there costings and they are charging £7500 for the same service.
All sites should have a blog attached they are great for natural listings.
The thing is if you consider the money companies pay on say CPC or banner ads its a great investment that will last unlike say a banner advert for 12 months.
