Target list building

Hey dear searchers!

I identified a niche industry and geographic area I want to pursue an acquisition in.
Now, I want to create a list of all players / potential targets with as many details as possible (name/# customers/revenue/reviews/email/phone, etc).

What is the best way to go about it?

I thought about hiring someone via fiverr/upwork to create the list. Any experience / other ideas welcome! I want to do it quick and in high quality.

Thanks
