Good answers.
I think for you to have someone trust with what you offer, have some free vouch offer from the reputable folks that are willing to try your service. Many 1 to 2 bets would be enough to prove that you're really something.
There are many reputable forum members that may want to try it as long it's for free, like test/trials. Well, that's just a suggestion of mine because I've seen some did that in the past.
Shoot me a message on telegram and Ill give you a free pick.
Thank you for that but I don't want to be that person.
I think, if you've seen no one then just put those picks on public and let the crowd see that you really are something else and you're proving yourself with it.
And from there and when the doubts are gone, you'll see people talk about what you've just done.
