I rent out time on my LA (HQ Avante) I offer a two hour lesson to get the new clients familiar with the machine and take them through as many of the different types of quilting as I can within that time. Customers can then rent the machine at an hourly rate. The time it takes them to quilt will depend on the type of quilting they want to do and the size of the quilt.
I am not sure if we will ever be really profitable but the clients we have had so far love the service we offer, they get to complete their projects themselves, and I get to meet lovely people and can put some of the income we receive to offset the money we paid for the machine. Everyone wins!!!
