I am going to someone to comment on blogs

hi
I am thinking of hiring someone to comment on blogs.
I am wondering what kind of motivation I can give so that the worker does a good job.
if i pay a flat rate for effort, worker can say he tried them all and they all didnt approve it.
these are the kinds of blogs that are autoapprove but cannot be used with SB for one reason or another (require login, have fields that SB doesnt recognize)
obviously, the higher PR ones are harder...so to give the worker motivation to comment on the higher PR ones, should I pay according to PR? for example, 10 cents for PR6 and PR7, 3 cents for PR1, something like this?
basically i am looking for guidelines on how to get the best results, and what pitfalls to avoid.

I don't have much experience with SEO but I do with employees. I found the best way to motivate them is with some sort of profit sharing, in that, relative to the amount of money they have made YOU they get a small bonus.

You hire someone to comment you have to train them and then pay them to maintain a list. There are probably lots of people who are already trained and who already have a list they maintain. Might be more cost effective to find someone who already knows how to do it, already has a list ... bypass the training curve and the list development time.

Don't know of anyone in particular but you could check the BST section.
