How to handle 300 link trades?

[troy]

Hi all,

A have a couple of bukkake sites that are online for 1 to 3 years and have pr 2 and 3.
Now a sponsor of mine have put about 300 related sites online and I want to trade with those sites but I am not sure how to handle this.

They are all relativly new sites with no pr or pr1.
They look all the same except for the domain name.I adviced them to use more text according there domain name which they started to do by using a H1 text at the top of the sites and they said they will add more text in the next couple of weeks.

Can someone advice me how to proceed?
Must I wait a little longer, I don't now if all sites are already index by the SE's.
Do I trade with all sites?
Is it better to do non recip trades?

Thanks in advance.
