The profit for 100 Site Shops Quests is 603,653 MP and took 50 minutes to do.
The profit from 300 User Shop Quests would be around 894k and would take the same amount of time.
Conclusion: Pay the higher amount for user shops, it is a lower amount of profit per quest, but faster to complete and more profit overall in the same amount of time.
