In a few minutes you will have a guy called Tim coming here and pretending to be the guy you must hire. haha please go to youtube itself and scan the cryptocurrency channels and contact those youtubers directly. They even have their emails listed or you can just leave a message on their about section. Much better than hiring jokers that'll come here.
How come it is possible to give such a perfect guess. As you've mentioned the very next post is being made by him. Anyhow it is your headache, we don't have youtube related to cryptocurrency and if you're willing to publish ads then it is fair to have it on our channel contents.
I am flattered to be so well known on this forum. It can't be because I am one of the only if not the only person to offer such a service. Plus I have a lot of other services that have had a lot more volume than my video production.
