When it comes to buyers, most of the ones I meet are very nice. However, you get some that are very demanding from the start and demand the world. If you send me a message that demands more from me and is strict from the get-go, you can be sure you already lost my help on the project.
I absolutely do not tolerate prospective clients who “demand” and want to pay me a pittance. I understand you have rules, but come on, this should not be your lead-in in the message.
It’s only off-putting.
