Its always worth a shot however the market is heavily saturated at the moment and it takes many hours and a lot of planning and effort into marketing yourself. She has to WANT to do it and understand it isn't easy to make a quick buck anymore.

Its a bit tricky and could back fire.
Non of my 'friends' know I work in sex industry and I would like to keep it that way.
Personally, to prevent losing a friend and/or starting a rumour in my circle..... I would test the waters and drop it in conversation and say a former work colleague is doing this to make ends meet and see her reaction....... ive tried it and the reaction i got ....lets just say I was super glad i kept my business to myself .

In my experience no good deed goes unpunished

I decided to tell my friends what I do and most of them are cool about it so depends if you think your friend will be too.

Anyway I told one of my friends about it a few years back after a few glasses of bubbly and she seemed really interested. Roll on to today and she's working now and loves it. We even do duos together too which is so much fun.
