Hi, I'm a new-ish programmer working on my own Unity 2D platformer, but I would be happy to help with your project. I really like your art style, and the game you posted on your profile looks super neat. I only have a few months experience, but I'm fairly solid, and I should be able to help with the items you've listed. (And if it turns out you don't want to use my work, I won't be offended).
