I have a logo for Richard Chamberlain Golf Design and have had this company since 2008.
I have been designing mini golf courses since 2015 however now want to brand them separately.
RCGD logo is attached. It would be ok to somehow link the same logos however if its completely different that wont be an issue.
If you use fonts that require a license, confirm with the client they're ok with it. For licensing reasons, it is better to provide your client with information on how to acquire the font rather than providing the actual files.
