link building/ providing links

To build backlinks and pagerank for my website which is 2 months old and has a page rank of 3 with 2500 current backlinks which are yet to be spidered fully by Google, you can create a links exchange page on my website and gain recipricol links and/ or aquire non-recipricol links, I am open to both options please provide me with proicing that is applicable to a yearly term. We are wishing to aquire links in bulk on a yearly term that have a page rank of 3 and above and can be renued, these should primarliy come from websites with general ecommerce content, no hate of xx sites. Look forward to your reply, Happy Bidding!
