Hello, In next 1-3 weeks I want to start some advertising campaigns so I'm looking for 2 types of advertising: - pay per sign up (it's about strategy browser game - I'm available to pay between $0.03 - $0.10 per sign up) - pay per sale (it's about shared host platform - I'm available to pay $2 per sale/lead - total cost of user/visitor will be $3) It's here any ad network available to offer this type of services?
