Looking to purchase permanent backlinks on high authority websites like Washington Post, Tech Crunch etc...

I am looking to purchase permanent backlinks on high profile news sites, I don't care where on the site (editorial or otherwise) the links are, if they are in custom content about the target site that is even better. The links will be to a legitimate long term established online company. Please send a list of sites where you are able to get links/content posted as well as the one time cost.
