A Union Editor would get around $27 an hour.

Your rate as an Apprentice would be $27. an hour or $1099 a week.
Since you have very little experience you should be very flexible with your rate. It is more important to get credits than it is to get a rate. Keeping this in mind I'd say around $20 an hour.
You will probably get more out of the experience than money by learning new ways of working and also making new contacts for future work. Keep this in mind when asking for your rate.
Good Luck,
