My usual rates for link building are $1 per PR1 link, $3 per PR2 or PR3 link, $5 per PR4 or PR5 link, $6 per PR6 link and $7.50 for anything higher. If you'd rather work on a flat rate basis I will get you 30 links for $100. Hope this makes sense, but if not or you have any questions please let me know.
