The basic rule of blog posting - at least in my book - is to write like you're talking to someone, and I can definitely deliver that, whether you're looking for someone to simply give you a starting paragraph or ghostwrite the whole blog post. That's entirely up to you. I've jumped through a lot of stylistic hoops to complete my Creative Writing degree, so I'd be able to do either one while retaining your "voice" to the best of my ability.
Also, on a "personal interest" note, I'm pretty pop-culture savvy, so a movie blog sounds like a pretty interesting project. I'd be totally on board if selected. :)
Thanks for considering me, and feel free to send me a message if you have any questions!
