good day Sir,Ezra4ever you can order t-shirts and all sorts of clothing and have it branded with your logo or design but the websites I have seen usually don't like short clothing runs and would prefer anywhere between 5,000 -10,000 or more as a starter to own brand your items. There will be exceptions to this rule but you have to find them. If anyone knows of them maybe they can share them here. If you are not stocking a lot of the product on your premises and prefer smaller orders then this I have found to be costly because they would prefer you to buy in bulk and if you don't you are stung hefty postage charges some not even valid charges.
I'll give you an example I used to buy corsets for my website at 12-16$ a pop but they add between 20$ - 40$ on for the postage and some countries get stung even harder. So, you product that looked appealing to sell becomes really unappealing to buyers. You have to have buying power to get everything delivered at a good price and the more you buy in bulk the more the price comes down.
I loved running my lingerie website and the idea was on small is cheaper to post around the world but this came unstuck by the end and although the website was making some money it was not worth continuing due to high postage costs that the customers inevitably have to pay in the bundled price. My site was primarily selling in ones and twos but selling in bulk to other stores is a better option. My other problem was I wasn't selling to a local market so this was another reason why postage was a big factor for me. There are easier ways to make money. If a Chinese manufacturer is for you then choose well. I was using a dropshipping service so you are the middle man or woman for a third party supplier to your customer.
I can pm you a dropshipper if you want to check them out, you may find some other links from this or at least see some rough sample prices.
