How tomanage someone else selling my advertising space?

Hey,

Unfortunately I don't have enough time to manage (sell / update) my advertising space on my network of websites as I am working on developing / expanding the network.

I wanted to get someone else to do this for me and share a % of the income but I don't know how to manage it or make it fair.

Advertising will be sold in slots of 1 month, 3, 6 and 12 months.

How could this be managed if for example someone does this for 1 month, gets 3 advertisers at 3 months but then stops working on helping advertisers, getting new advertisers etc. - How do I make this fair for both sides?

Thanks for any help

 

i think you can give him 10% or to make it more appealing, make it 40% commission.

 

Thanks for the reply

Yes, it will be either commission or CPA..

But this, I already know, managing it and the details are what I want help for.
