Hello!!!
I've gone through your description and feel I would be a good candidate to proofread your material. You're looking for someone to clean up the grammar, syntax and spelling of your texts and I feel I am that person. With my help, the consistency of language you require will be assured. I'm a native English speaker with a vast amount of proofreading/editing experience. I plan to read all your material several times to stamp out any mistakes, that's how meticulous I will be with your work. I would like to discuss more about your project, feel free to contact me. Hopefully, I get a chance to show you my quality of work. Cheers!
