Need Advice on Starting T-shirt Side Business

[Xeon_Ond]

Hi all,

I'm currently a full-time graphic designer, but would like to increase my monthly earnings by starting a side small business selling t-shirts with my art on it (I can draw).
Basically, the t-shirts will have a certain consistent style of art on them, all sold under a funky brand name.

The execution and order fulfillment part is not the main issue, marketing and getting the product out is.

Because I've no experience or contacts or knowledge in this apparel industry whatsoever, is it better if I "deposit" my t-shirts with these small apparel start-ups and I give them a 30 / 70% commission (70% for me) for every of mine item sold?

please advise. Tks!
