What are your skills and where do you live?
To be honest, based on threads about this in the past I wonder if there are more practical things that would bring in urgent cash - ironing, cleaning, pet-sitting etc.
My dc's piano teacher told me recently that she makes more money pet-sitting, of all things, than teaching piano. She and her husband did some flyering and put up some signs in local shops and the requests came flying in.
£20 printing a stack of flyers, a couple of evenings putting them in letterboxes around you offering ironing, cleaning, pet-sitting or plant-watering (it's holiday season after all) or all of the above as a sort of "house-keeper on call" service will almost certainly yield more than online sex work.
Apart from anything else, you will be paid a pittance doing online sex work, and on an hourly rate, you can't compete with a woman in eastern Europe or Asia. Then you have to wait for the money to reach your account etc. At least with house-keeping related work you can ask to be paid in cash. Sort out your taxes later on if you decide to keep at it.
