Hi, I would suggest you check out T-Shirtforums.com it's a great place to get information and ideas on how to set up distribution, stock and more. I personally am also doing heat transfers. Get a heat press instead, it will save on your arm and the transfers will come out better. You need an even pressure and heat for good results.

Think of 'Who is your target customers?' that should help you decide how to get your product out there. Check out craft shows and see if people are sell/buying shirts there. There is also the internet. Creating a web page isn't too difficult. There is software that let's you drag and drop.

I too am working on getting my business licenses. So until I have them I am selling some shirts on eBay and am looking into etsy.com too. Like I said just check out T-shirtforums.com you won't regret it.
