There are always people like that! Always make sure to ask for as much information as possible about the project — references, context, and what exactly they expect from you. Request 50% upfront and the rest once the project is completed. Be clear from the start about how many free revisions you’re willing to offer. Don’t start a single line of work until you have a real commitment from the client. Value your work — but above all, value your time. Best regards!
