Freelance work for a client

I received more work from another client the other day asking me to design his company logo, I have charged him £150 and am currently working with him because he is able to bring me more clients who I can potentially work with to earn more money.

This is a business owned by my client called water, who wanted a specific colour scheme of yellow, orang and white because it need to match the theme of his shop which was yellow based and these are all close colours which work with one another.
