In my journey I was able to build recording clientele by offering a free hour with a 4-hour paid block of studio time. I would offer a free mix with a recording session sometimes or I would offer a percentage off for first time clients. Also, using a referral system helps, if I have a current client I may tell them I will give them a free hour for every client that was referred by them. All of these worked for me at some point in my life. What has worked for yall?
