I am also in need of this.Searching a lot but no success.I think real money would be great.Lets say advertisers want to target certaing groups then they need to go through a payment gateway and pay us money.If the groups would be ranked based on the activity and based on those ranks we can assign the amount the advertiser has to pay.Or it can be through a bidding process, lets say 10 people target a certain group and bid on the group then the bidder with highest average amount per day would be considered or something like this.Just a vague idea.I am not a developer, just an idea so that some developer can work on this if many people require this.
