Ask HN: How would you make $1000 from $20 in 90 days?

This is just an idea. It being feasible depends if it goes viral. Use the $20 to run a VM for the 90 days. Host a minimal viable product with different micro services that people will want to use, and charge like 1-5 dollars depending on the microservice. One microservice could be: A person uploads a recording of someone talking, then it gets transcribed and emailed to them as a word document. All must be automated.

Hope this give you an idea. cheers.

90 days is 720 work hours.

Your goal is to make (1000-20)/720 = $1.36 per hour.

You can literally do any job and you will make much more.

With only $20 it's more about what service skill you have to offer. And that's not enough to even advertise. So, you would need to go door-to-door offer your services. post of craigslist or facebook etc.

You can try selling hot-dog?
