99designs was great to use. I would definitely use their service again.
We do professionally screen printed shirts, printed on demand, and drop-shipped to your customer.
Please take a look at our current logo at http://shirtbot.co .
You can see the green robot there. I want to make a robot "icon" with more of a "3D" feel to it like most Mac App icons. For example, I've had an icon designed in the past for a software project - http://wealthinspector.com. I also really like the icon used on http://shopify.com.
The catch is that while I want this robot to look a little more 3D like the shopify icon, it still needs to be able to be flattened to a single color and still look like a robot. In other words, I need a "mac app icon" that can also be screen printed or embroidered on a shirt or jacket in a single color and still look like a robot.
Notice how the shopify icon shopping bag looks nice and 3D, but if you added a single color overlay (e.g. in photoshop), you would still be able to tell it's a shopping bag.
The robot that I have up there already is a good starting point, but I need to make my robot materially different than this one. One thing I like about the existing robot is that it has a large, flat box chest/abdomen - I am going to have a video animator use this robot in a video where t-shirts are flying out of a hole in his chest - as if he is a shirt-producing robot.
Another thing I like about the existing one is that it is sort of "retro" looking.
The icon needs to be delivered in large dimensions of course. I can always scale down to make smaller later. Large means at least 3 inches wide at 300dpi (or perhaps I can vectorize later?).
I've attached the shopify logo and the current shirtbot logo.
