I'd suggest reaching out to AWS about this. Explain the situation. AWS has a number of programs for startups that you may be able to apply for, including one that includes 100k worth of credits.

Also, if you can't afford to scale to new customers... stop? I'm sure it probably sucks, but like, does it suck more than having no runway? Seems like you'd be best served slowing things down and spending some time with AWS on cost optimization.

There aren't a lot of details to go off of here so I don't know what more advice to give.
