I can provide you incentive installs from my own userbase (my house ads solutions):
cost / install is $0,30 for any country + after campaign complete, report with xml file
can generate for you 500/installs a day for tier 1 countries like USA, UK, Germany, Canada
or 1000/installs a day for trier 2 and 3 countries
Why price is not cheaper than others? I offer real users, no bots.
