What is an emotionally intelligent response if a model reaches out because he or she would like to be paid to collaborate with you (the photographer) if you are not excited about working with them for a price?

This is for situations where I was not the first to message the individual although I may have advertised that I am looking for a model.

I can't help but feel that any response at all is base and selfish no matter how you dress it up. However, ghosting someone is also impolite. In my case, taking photographs is not 'free' because I use an analog workflow. Every frame costs me money and quite a lot of time to from click to print.

This question only applies to working with strangers. Cost is not a factor for my friends or family, and I am always excited to capture them on film.
