I haven't used the program, but I would be planning to use something like that, over time. This is what is used by
My Pornstar Blogs, for example. It does and tracks link exchanges, for all their sites.

This should be fairly easy to make, and could be priced at around $100 or more. I would say that ROI would be guaranteed.
### Edit:
The new one could be better, based on how things work now. Option of adding multiple anchor texts, for example, and other things like that.
Program like that seems to be a very good thing, for xxx sites. I would say that it is probably a big part of why they sites have good search engine results (mostly Google).
