One-Way Backlinks Required

I require 50 non-reciprocal backlinks to my dating site. All the backlinks must be PR 3+ with a sprinkling of PR4, PR5 and PR6 links if possible. The backlinks MUST be one-way and relate to online dating, matchmaking, relationships, singles, etc. I will provide keywords for the anchor text. Preference will be given to anyone who can submit a proposal that does not just include submitting to directories. I only want to use directories as a last resort. Payment for this project will be placed in GAF escrow and paid when I have received reports and links to the sites. No other payment method will be considered so if you do not want to use GAF escrow please do not bid.
