you don't need much in terms of starting capital. i didn't have anything to start with. first of all create a profile on AW, it's free to have the profile, verify yourself and add some photos to your private gallery so you make some money for aw advertising. show your number and put yourself as available today whenever you are free. can you work from home? then do incalls. if not, do outcalls only. once you have made a couple hundreds pounds you can rent hotel rooms to work from for incalls.

If you're at immediate risk of becoming homeless, please ring Shelter - they can advise better than anybody here can. There are also organisations where you can get food; do you have a food bank or community pantry near you, or even a project that serves meals to those who need them?

Your previous posts say you're in Manchester - is this still the case? There used to be a lot of parlours in that area but I don't know what it's like now; maybe ring round and see if you can get a shift just so you have some cash quickly? They might even need a maid or a receptionist, and you can get on with setting up an AW page while you do all this if you want to

As Amy said - if it were me with no place to work from and in need of money urgently I'd phone around "massage parlours" in my area to see if they need anyone.
Any place that advertises lots of girls or different girls each day of the week - that's a brothel and they might need someone. Your take per client will be low but it will be instant with no outgoings. You should definitely earn something that day.

There might be a clothing requirement. Just do your best and they might let you work in whatever you have or --- for example -- I worked in places where a massage uniform of a certain colour was required. But many girls would turn up without the right clothes and often someone had a spare.
