happy to show you my work by getting 3 of your terms onto page 1 (depending on keyphrase difficulty). I currently rank in the top 5 on google for a site I seo for used vans, used van, van bargains, used van offers.....
May I ask if you have your site setup in google webmaster tools and have you submitted XML sitemaps to google and bing? The task is far easier to accomplish of your domain is established and has had the appropriate level of background SEO performed.
