There are many ways to contact them. You can check their streaming channel and find their social media accounts that they attached on their profile info. Like this for example, I found shroud's twitter from his twitch account and saw his business email on his profile.




It's hard to suggest some streamers I know because we don't live in the same county. It will also depend on your budget because as far as I know, streamers that promotes a gambling platform asks for some talent fee first before they do the job. More followers means higher talent fee because their viewers' reach is huge.
