Creating an AI powered Trip planner workflow

Hi guys, I am creating a AI powered Trip planner workflow.
You can get your trip planning by just filling a normal google form.

I am using a free plan which is giving me 1000 operations per month only. There is one hurdle to make it live and it is if I am set a 15 min schedule where cycle auto run and consumes 4 operations every 15 min. Due to that all the free operations ends in 3 days only.

Hey, creative people pls guide me how can i crack this?
