@mrjonezz don’t bundle “cloaking + media buying + free POC” in one ask, that’s why you’ll mostly get random DMs. The guys who can actually run Meta without burning everything usually charge for test phase, even if small.
What I’d do is ask for a paid 3-5 day test with capped spend, clear KPI, and you provide throwaway assets only. Don’t give anyone your main BM/pixel/domain. Screenshots are easy to fake too, so ask for live screen share of past campaigns or at least some real logs.
Also depends a lot on niche... nutra/crypto/sweepstakes/dating all behave different on Meta, so if you don’t mention vertical nobody serious can quote properly.
