Hey BlindPassenger! Welcome. There is a thread of active Betas
here where Betas have listed their skills. You can PM or email any of them with what you're looking for.
You can also post a thread like this and list out what you're looking for in a Beta and someone should respond if they're available.
I second Vicki's comment about Grammarly for grammar and punctuation. That typically works for smaller fics but the longer you get the more in need of a beta you are. I'd start with the thread and if you don't have luck there then start a "Looking for a Beta" thread here and go from there.
Good luck!
