I'm vouching for bitmover.
Though I've never had any personal interactions with him, I've always been struck by his knowledge and experience that I've seen around the forum for the years that I've spent here, and I must say that any project, platform, firm, or company renting his signature and avatar spaces wouldn't be wasting their money, it will all be worth it, without a doubt.
Whatever I said might be flattering but it's the truth. He is one of the most reputable and experienced members of the forum and I say this from my own experience here in the forum.
I wish you good luck with any ventures you get into from here onwards.
