Never written a comic before, but I bet it's at least a little like a script, and I've written those. From my perspective, however, what you need most is someone to check your grammar and provide a bit of feedback on the content. I'd be willing to do that for a share of any profits that result. I'm not sure what percentage is fair, but I'm sure we can work out something. If you're interested, I can show you examples of my recent work.
