200 applications in 2 weeks for $1.5 in niche

In 2 weeks of work on the projects we managed to generate 200 applications at an average price of $1.5$.

Of these applications by customers in 2 weeks became 12 people and yet 40% of applications continue to be processed and the work with customers continues.

With an average check of $900 and the advertising cost of $300, the profitability of investments was (900*12-300)/300=3500%

I say, the daily budget was limited to $12 because the customer simply failed to process all applications.
