Let's calculate, how much will they buy in a week. There are 10 people, each person buys for a 16*7=112 hours/week. Assuming 1 ticket in a 5 seconds we get 112hours/5sec=80640 tickets a week, times 10 we get 806,400 tickets a week which is not even half of the amount we need. Project can not be completed in a week.
