Hi everyone, I'm relatively new to freelance and have recently been assigned a task by one of my clients. When this client was starting his first company ten years ago he worked through a different designer. Now my client has a second company on the go and would like to use one of the concept ideas that were presented to him those ten years ago. The old designer gave him permission to use the concept and gave him a quote for the logo. Now the client has come to me and asked what my quote would be. I'm quite unsure of what to do in this situation seeing as the design is not my own. I'd likely be turning it into vector and hashing out any tweets to the design if there are any. So, my question is how much I should think about charging seeing as the design isn't mine but I'd be creating the vector file?
