I move on. Not all clients are your clients. Cheap clients want cheap photographers. You're not in their price range, and that's fine. There's not much you can do to combat it apart from putting a basic pricing guide on your site, or saying your commissions start at $XXX.
Photography
A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
Imagine you're in the market for a new kitchen. You get quotes from 10 companies.
Will you contact 9 of them that they don't have the job?
Welcome to life.
Not sure what you're expecting? You want people to email you back saying you cost too much? What would motivate them to do that? It's not like they get anything out of that
Put your pricing sheet on your web site. Potential clients will then filter themselves, allowing you to concentrate on the ones who can actually afford your service.
It's common..it means they're shopping around and getting pricing from different photographers and they decided not to go with you. Nobody owes you anything until you've got an agreement/contract.
