Quality Link Building

I am after someone that can build quality backlinks, articles? for an automotive website (car detailing), the backlinks must be quality backlinks with a good Google PR and related to automotive, i do not want it submitted to link farms/link exchange? or non english websites. It currently has 1400 backlinks already (mainly blogs), i am looking at increasing this to over 3000 backlinks if possible. Experienced SEO workers only - 1. Must provide examples of websites you have done SEO and link building for. 2. Explain what methods will be used. 3. Estimate of time to complete project, i am not looking at building thousands of backlinks over night. 4. Keywords will be given to use as anchor text if possible. If the results are good we will continue to do ongoing business.
