I would as above look at Fusion360 easy to convert 2d to 3d something to show the customers free trial period, free for hobby use and good price on licencing if you decide its OK for your business, its something thats developing fast and will grow where I suspect many packages are stagnant and offer less for more. It costs nothing to take a look, with no cad cam experience I was producing basic work within a weekend and continue to learn with each use as an ex bricklayer/ general builder with lots of joinery experience it would be my choice if I were to design bespoke cabinets now, and easy to change dimensions as required or parametric as people say.
