How much did your business make from using Influencer Marketing?

I own an online business. I am in touch with an influencer with 179k followers, average post gets about 5k - 25k plus likes with 100-300 comments.

They want $2000. They fall within my businesses niche for sure. I have never hired an influencer to this degree. Has anyone had success with an influencer after paying a high amount? I own a small business and am just worried if it is worth the marketing expenses or not.

I appreciate ANY advice.
