Need SEO provider w/ permanent links for multiple URL's

We are looking for an SEO provider to offer permanent links to increase rankings for multiple URL's.

The keywords that we are trying to rank these URL's for have almost zero competition.

We need different links for each URL so that there are no footprints.

If you are able to do this and increase ranking for the URL's that we provide, we may be able to pay for a monthly service to maintain and increase rankings for these URL's.

Please do not apply unless you can provide permanent links that will increase rankings without any penalties and without any footprints.

Please note that even though our max price is $500, the provider who can offer the lowest price and give us results will get this job and the possibility for an ongoing monthly job with us.
