Price for hardlinks
 

I have about 60 blogs on sensualwriter and thumblogger and 10 on .com .net .org, about 10 are pr1-2. what will be the price I can get for selling hardlinks per month?

It depends on buyer. Someone can buy it for $500/year other for $50...

The price of any backlinks depends on its quality.
SEO wise 10pr1-2 won't cost more that $50 a month.
But if the sites have high traffic and those backlinks can generate some traffic for advertises then they can pay more.
