Need advice on growing my sewing business!

Hey everyone, I'm reaching out for some help and guidance. Over the past year, I've been pouring my heart into my sewing and embroidery business, specializing in creating memory-stuffed animals and personalized embroideries from loved ones' clothing. I truly believe I have a unique niche that I could really grow, and I don’t want to give up on this dream. While I've had some success at craft fairs, I'm struggling to turn a sustainable profit and grow my business further. I'm at a point where I could really use some advice and insights. Do you think hiring a marketer is necessary, or have you found success through other means? Your help would mean the world to me as I navigate this journey towards making my dream a reality. Thank you all in advance for your support and wisdom!
