I'd like to tell you to chill, but you don't actually have a lot of time to finish those 8 pages. Especially if you want weekends off (I have no idea what your schedule is like, lol). But supposing you want to be done by the start of September, around 1.5 pages every two days. However if that 10 hours takes into account drawing, inking, coloring, you might be able to work faster if you do batches. Say 3 pages of drawing then ink then color.
Basically try not to over work yourself, but don't put it off too much if the deadline is strict.
Also good luck! I know its like walking through muck right now, but the finish line is getting closer!
