CRM for event/project management

Hi all. Im kinda new to the CRM world. Ive newly started a company where I do booking/event management/project management. I noticed after just a few weeks that I need a place for all the information, customers, artist, plans and projects, and not just OneNote. We can exclude all the sales and potenially marketing aspect of the CRM. Do you guys have any recommendations? Its just me, newly started up with this, also with a 9-5 job in marketing.
