Adding to my last comment but you should also consider the people who are in high school/collage and are applying for this as an extra payment sort of work. As a student myself I'd like to know if these hours are flexible around my schedule because I could possibly miss important meetings with the DV staff for upcoming projects and people such as this may be looking for ways to expand their work knowledge and get more hands on experience but have limited times that they cannot do so. So for the students, people in different timezones, OR other it's important to make a note that you're flexible for schedules and such.
