At this burn rate, I’ll likely be spending $8,000 month,” he added. “And you know what? I’m not even mad about it. I’m locked in.”

For that price, why not just hire a developer full-time? For nearly $100k/year, you could find a very good intermediate or senior developer even in Europe or the USA (outside of expensive places like Silicon Valley and New York).

The job market isn't great for developers at the moment - there's been lots of layoffs over the past few years and not enough new jobs for all the people who were laid off - so you'd absolutely find someone.
