I would even recommend decoupling the processes a bit. That is - start with a known good schematic, ideally one that exists as KiCad schematic already (look for KiCad projects on Github). Practice creating a board outline, placing some parts and routing traces, make yourself familiar with the tools around that (how to deal with layers; how to use the design ruler checker; the 3D preview to find blatant mistakes with connectors or so; how to export the files (if necessary - Aisler accepts KiCad files for example)). If you want, export it and order it. At JLCPCB that should be $2/2€ + shipping if five pieces and HASL is good enough. Then maybe enter a known good schematic oneself. Then create a simple circuit on breadboard, turn it into a schematic, enter that. ...
