You probably aren’t quite at a place where you can afford to outsource all your design to a professional designer.
This is mainly for two reasons:
1. Limited financial resources
You’ve got to be very strategic where you invest your money. (Ex: if you’re a gym owner, do you hire a designer or a new trainer? – No contest; you’re going to invest it in a trainer who can expand your business.)
2. Your brand identity is still fragile or in-development
You’re still teaching this baby to walk, and you need to keep your hands directly on each visual and word that your company puts out there.
