Voice over for video courses

Our team wants to hire voice over on one big and interesting project (a minimum of one year). We are a team of engineers and we make video courses. We want to sell our courses on platforms like Udemy. Given that none of us are not the native English speaker, we want to hire professional voice over. Voice over is important part in this project, we want you to be part of our team and we want to offer you a professional contract and 10% of monthly sales. Our plan is to publish at least 1 courses per month.
