My excellent communication skills in English makes me the perfect candidate for this project. I am willing to propose this arrangement: I will charge $30 for the project but if for some reason my work is not up to par with your standards, I will not charge for the job, or I am prepared to return the payment even after three clearing days. Nothing egotistical or negative about it, but just pure professionalism on my part, along with the continued yearning to learn more, and improve on my skills.
