starting my clothing brand

I've been dreaming of starting my own clothing brand for a while now and I'm finally ready to take that plunge. My clothing line will focus specifically on T-shirts, and although I'm open to exploring other types of clothing in the future, for now that's my main focus. I already have a design concept in mind, and I'm looking to target a youth customer base. I'm in need of an experienced freelancer to help me turn my vision into reality and turn my clothing brand into a success. i have my llc and website just new to figuring it out how to make it work
