Horror Aficionados discussion

I wonder how many authors this group includes. A lot, I guess.
So, will you help me with something. I'm new in writing business. I'm going to publish my first book, but I don't want to rush it.
Authors, where do you find beta readers from? I know, some of you send your books to your friends, but I don't want to give to someone who already knows me. Is there a place where I can find people interested in beta reading?

Thank you.

I'll show you mine if you show me yours. I do review exchanges all the time, where I read and review the books of other authors and they do the same for me. I'd be happy to do a beta-read for you, H.G., if you'll do the same for me. Fair?
