The Internet would be a problem. Depending on your cellphone plan, if you have the ability to tether with unlimited data, that could be your home internet. I would not try to work like that if you don't have good 5g coverage and unlimited tethering.

For the computer, companies, if they're legit, would provide you a computer to do the work they need you to, assuming it's a regular w-2 job. Only contractor/1099 jobs are where you have to provide your own equipment/materials for the job. Obviously you'd have to figure out a way to land a job in the first place via the internet, your local library would have Internet access I'd hope.

Hope you can get something to happen for you.
