Salary for entry marketing positions in london?

Hi I (26F) will finish my second masters in luxury marketing soon, I have been doing a marketing internship for a brand (as for visa reasons I wasn’t able to do a full time position while on my masters). I am already applying even though I only finish in January, and would love to know what salary should I accept and is more raisonnable. And as I am applying to luxury conglomerate is it ok to start with an internship there an hope for a permanent position ? If so on what salary? I really need help concerning salaries as I am not from london, have two masters and don’t want to be settling for less than what I deserve
