If I lived in that area I probably wouldn't respond because the ad is too vague....like click bait. Instead of enticing drone operators with a paycheck or a challenge, you're playing on their sense of curiosity, just like click bait does....just to find out that there's no pot of gold at the end of that rainbow. At the very least you should list the nature of the testing. There are many ways to earn a paycheck with a drone. I've been doing it for years. Up to now, "Testing" hasn't been one of them. Plus the word "test" is conducive to "stress" as in "stress testing." Are we load testing? Speed testing? Wind testing? None of this sounds appealing to someone with a $5K investment.
