At least you could upload the img so we go to our local custom shirt factory instead of buying it overpriced online.
At this point, any comment about fair compensation for creative work would probably be hypocritical, but it's one of the reasons why patents get enforced (and ironically, it's what Verdes is doing), so I'm not even going to fight it, but I'm not going to give it away for free.
But, I'll letcha in on a little secret. You think the shirt is overpriced and not worth whatever it's set at? Fine. While I used Adobe Creative Suite to put it together (a software package that usually costs a thousand bucks if purchased legitimately, which I did), nothing is stopping you from creating something similar with a DIY fabric transfer kit, an inkjet printer, Microsoft Word, and an old t-shirt. Hell, didn't get MS Office installed on your system and don't wanna spend the money or put your system at risk by Bittorrenting it? Download OpenOffice, and it'll do a comparable job. You might even be able to create a better design than me.
Will you get the same results for cheaper? If you buy a bunch of shirts in bulk and do it all by yourself, probably. If you "know a guy", then definitely. But if you just want ONE, your per-unit cost is always going to be higher. A 6-pack of transfer paper alone will run you about $12 (and they do NOT sell individual sheets).
