Ad network with free trial ?​

Hi folks ! i'm looking for good ad netword with free trial (i mean, free click or free display…) so you can test the network…
i've already tested bidvertiser but the quality of traffic i receive do not match my needs and their auto-refund program really burn your bank account…
so anyone know one good ad…
