I know it takes time, but:
Set up an exit "hub" that you can send to even based on niche.
Find several multi-niche sponsors or whatever sponsor you choose.
Dump the FPA's into a rotation script and fire ALL exit traffic at them. Push for a few weeks, see what is converting, figure out what per exit sent you are getting for each one and increase the weighting you are sending the traffic to.
Add new methods every week and always be calcing the per exit rate. Adjust traffic based on that but NEVER send all your traffic to one place, no matter how well per exit it is paying. You need always to diversify.
You will get a LOT more than $0.003/exit doing this.
But if you are looking for a quick send solution, I am not sure. Pete from exitcoin used to pay honestly for my traffic, but they don't accept outside traffic anymore.
